In this paper, we prepared a series of Ce_1-xTi_xO₂ (x = 0-0.20) nanorods by hydrothermal method, which were used to construct the PdCu/Ce_1-xTi_xO₂ catalysts. The Ce_1-xTi_xO₂ and PdCu/Ce_1-xTi_xO₂ samples were characterized by transmission electron microscope (TEM), XPS, N₂ adsorption-desorption, X-ray diffraction (XRD), inductively coupled plasma optical emission spectrometer (ICP-OES), etc. Catalytic activity, stability, and repeatability of the catalysts for methanol oxidation were investigated. The results show that doping a proper amount of titanium could strengthen the interaction between Ce_1-xTi_xO₂ support and PdCu nanoalloy, thus increasing the oxygen vacancy concentration and promoting Pd species with a higher oxidation state. These modified properties are beneficial for the deep oxidation of methanol. The light-off temperature (T₅₀) and full-conversion temperature (T90) of methanol over the PdCu/CeO₂ catalyst are 10⁸ °C and 159°C, resp. The greatest activity improvement is found for PdCu/Ce_0.9Ti_0.1O₂, which shows the lowest T₅₀ of 88°C and T90 of 138°C. Furthermore, neither PdCu/CeO₂ nor the modified PdCu/CeO₂ catalyst produces byproducts and exhibit excellent stability and repeatability throughout the whole test period. This study provides a reference for in-depth understanding and designing of efficient and stable CeO₂-based oxidation catalysts. This study involved multiple reactions and reactants, such as Sodium tetrachloropalladate(II) (cas: 13820-53-6Computed Properties of Cl4Na2Pd).

Pd-WO_x heterostructures immobilized by MOFs-derived carbon cage for formic acid dehydrogenation was written by Zhang, Anqi;Xia, Jianhui;Yao, Qilu;Lu, Zhang-Hui. And the article was included in Applied Catalysis, B: Environmental in 2022.Reference of 13820-53-6 The following contents are mentioned in the article:

Formic acid (FA), a major product formed in biomass processing and CO₂ reduction, has attracted considerable attention as a promising renewable liquid-phase hydrogen carrier. Designing highly efficient catalysts for FA dehydrogenation is a key challenge for fuel cell-based hydrogen economy. Herein, Pd-WO_x nano-heterostructures (2.9 nm in diameter) anchored on ZIF-8 @ZIF-67 core-hell MOFs-derived nitrogen-doped porous carbon cage (NPCC) are fabricated for the first time through a phosphate mediation approach. Strong adsorption and dispersion of Pd²⁺ in the phosphate-modified NPCC are essential for the synthesis of highly dispersed ultrafine Pd nanoparticles. The alk. solution produced during the subsequent reduction process of metal ions can remove the phosphate. The obtained Pd-WO_x/(P)NPCC catalyst presents an extraordinarily catalytic performance (TOF, 2877 h^-1 at 303 K and 6135 h^-1 at 323 K) with a 100% H₂ selectivity and conversion toward FA dehydrogenation. The superior performance of Pd-WO_x/(P)NPCC is likely due to the strong interaction effect between Pd-WO_x and NPCC; unique structures of Pd-WO_x nano-heterostructures; and NPCC with hollow and large surface area and abundant surface defects. Kinetic isotope effect (KIE) measurements demonstrated that cleavage of C-H bond is the rate-determining step for HCOOH dehydrogenation. This study provides new insights into a facile and controllable synthesis strategy of inexpensive and efficient catalysts for high-efficiency dehydrogenation of liquid-phase hydrogen carrier. This study involved multiple reactions and reactants, such as Sodium tetrachloropalladate(II) (cas: 13820-53-6Reference of 13820-53-6).

Sodium tetrachloropalladate(II) (cas: 13820-53-6) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water.

And the article was included in Journal of Molecular Structure in 2022.Product Details of 13820-53-6 The following contents are mentioned in the article:

Treatment of two molar equivalents of 1,8-diaminonaphthalene-2-thione with one molar equivalent of the metal’s(II) salt (Pd, Pt, Hg, Cd, Zn) afforded both neutral thione complexes and thionate derived complexes. The prepared ligand and its complexes (1–8) were characterized via different spectroscopic technics including: FTIR, ¹H, ¹³C-NMR, and mass spectroscopy. The spectroscopic data anal. suggested that these compounds adopt different structural geometries. For instance, Pd(II) and Pt(II) complexes show square planar geometry. Whereas, thione complexes of Hg(II), Zn(II), and Cd(II) showed probable tetrahedral structure. However, thionate derived complexes of Hg, and Ph-Hg are expected to be linear. The thionato-Cd(II) complex show bidentate chelating mode through its N and S donor atoms. Furthermore, the newly prepared complexes exhibit nano-structural characteristics, which were measured by SEM and x-ray diffraction of the powder. SEM data showed that complexes from (3, 5) and (8) gave irregular nano-structure, nano-rod structure, and nano-sphere structural pattern, resp. However, Complexes (1) and (2) were tested against MCF-7 (breast) and LoVo (colon) cancer cells using MTT assay. The palladium complex showed a promising antiproliferative activity against colon (LoVo) and breast (MCF-7) cancer cells with IC₅₀ values 21.13 and 22.25μM, resp.

Highly Dispersed Pd Nanoclusters on Layered Double Hydroxides with Proper Calcination Improving Solvent-Free Oxidation of Benzyl Alcohol was written by Li, Jin;Wang, Qinglin;Yu, Shudi;Wei, Zhuojun;Zhang, Hui. And the article was included in ACS Sustainable Chemistry & Engineering in 2022.COA of Formula: Cl4Na2Pd The following contents are mentioned in the article:

Highly dispersed Pd nanocluster (NC) catalysts x-PdNCs/LDH-T (where x is the Pd loading, T is the calcination temperature, and LDH refers to Ni₃Al-layered double hydroxides) were synthesized by the electrostatic adsorption of atomically precise captopril (Capt)-protected Pd₁₇Capt₈ clusters (~1.4 nm) onto the LDH support followed by proper calcination. The 0.15-PdNCs/LDH-T (where T = 250, 270, and 280°C) catalysts show similar Pd NCs with sizes of ~1.6 nm highly distributed on the verge of small-sized LDH nanoplates (30-50 x ~15 nm), while the 0.16-PdNCs/LDH-300 catalyst shows slightly increased Pd NCs size of ~1.8 nm, attributable to the sintering between neighboring NCs. The as-obtained catalysts x-PdNCs/LDH-T all show excellent solvent-free aerobic oxidation activity of benzyl alc., and 0.15-PdNCs/LDH-280 exhibits the highest turnover frequency of 108,670 h^-1. This unprecedented activity can be attributed to the ultrafine Pd NCs with the complete exposure of interfacial sites Pd⁰/Pd²⁺-Ni²⁺-OH after removing the surface ligands contributing to the adsorption and activation of the reactants, the electron-rich Pd⁰ species stemmed from the electron transfer from Ni²⁺-OH groups to Pd clusters promoting the β-hydride elimination of metal-alkoxide intermediates and strong PdNCs-LDH synergistic interactions, while other catalysts with residual ligands or enlarged PdNCs along with less surface hydroxyls as well as a newly generated NiO phase exhibit reduced activity owing to the blocked or reduced active sites. Addnl., the present catalyst shows no significant activity loss after six runs, indicating its excellent recyclability. This study involved multiple reactions and reactants, such as Sodium tetrachloropalladate(II) (cas: 13820-53-6COA of Formula: Cl4Na2Pd).

A versatile route to fabricate Metal/UiO-66 (Metal = Pt, Pd, Ru) with high activity and stability for the catalytic oxidation of various volatile organic compounds was written by Li, Juntian;Xu, Zhiling;Wang, Teng;Xie, Xiaowen;Li, Didi;Wang, Jiangen;Huang, Haibao;Ao, Zhimin. And the article was included in Chemical Engineering Journal (Amsterdam, Netherlands) in 2022.Reference of 13820-53-6 The following contents are mentioned in the article:

The supported noble metal catalysts have been demonstrated outstanding catalytic performance for the catalytic degradation of volatile organic compounds (VOCs), but their high cost, easy poisoning and sintering deactivation limit their further applications. Herein, we proposed a flexible and universal strategy to prepare the highly dispersed metal nanoparticles (Pt, Pd, Ru) supported on metal-organic frameworks (metal/MOFs) through the impregnation-reduction method for the catalytic oxidation of VOCs. Metal/MOFs integrate MOFs with large surface area and high porosity for supplying VOCs adsorption sites and highly dispersed metal species for offering catalytic active sites. For example, Pt/UiO-66 NPs exhibited nearly 100% conversion efficiency and CO₂ yield for the catalytic oxidation of various VOCs including Et acetate (260°C), n-hexane (260°C) and toluene (180°C). Particularly, there was no obvious difference in the morphol., size, distribution, crystallinity, and composition of the fresh and used Pt/UiO-66 NPs from the TEM images, XRD spectra and XPS anal. Besides, a series of metal/MOFs (Pt, Pd, Ru) exhibited high reusability, good water resistance as well as excellent stability over 150 h on the onstream reactions for the degradation of Et acetate. Furthermore, the catalytic oxidation mechanism and pathways were revealed by the study of active sites and reaction intermediates via XPS, in-situ diffuse reflectance IR Fourier transform spectroscopy (DRIFTS) and proton transfer reaction-time of flight mass spectrometer (PTR-TOF-MS). We anticipate that this work may shed light on developing noble metal catalysts supported on porous materials for novel applications in environmental catalysis.

Unraveling 1-Hexene Hydrogenation over Dilute Pd-in-Au Alloys was written by van der Hoeven, Jessi E. S.;Ngan, Hio Tong;Yan, George;Aizenberg, Joanna;Madix, Robert J.;Sautet, Philippe;Friend, Cynthia M.. And the article was included in Journal of Physical Chemistry C in 2022.Application In Synthesis of Sodium tetrachloropalladate(II) The following contents are mentioned in the article:

Dilute Pd-in-Au alloys are valuable materials for selectively hydrogenating alkynes and isomerizing alkenes. By diluting Pd in a Au host, the selectivity toward semihydrogenated alkene isomers can be significantly enhanced and the unfavorable overhydrogenation to alkanes is suppressed. However, a detailed mechanistic study on the origin of the enhanced alkene selectivity over dilute alloy catalysts is still missing. Here, we combine experiment and theory to unravel the reaction mechanism, identifying rate-limiting and selectivity-controlling steps in 1-hexene hydrogenation over dilute Pd-in-Au catalysts. Using isotope-exchange hydrogenation experiments, we show that 1-hexene and hydrogen over a bimetallic Pd₄Au₉₆ in silica catalyst preferentially form 1-hexene isomers, (trans and cis) 2- and 3-hexene and only a small amounts of hexane. The reaction is consistent with a Horiuti-Polanyi mechanism, similar to a monometallic Pd nanoparticle catalyst. Computation of the free-energy profiles for 1-hexene hydrogenation and isomerization over a single Pd atom in a Au surface using first principles calculations indicated that the isomerization of 1-hexene to 2-hexene is energetically favorable due to the relatively large barrier for H₂ dissociation preventing hydrogenation to n-hexane. Microkinetic modeling established that H₂ dissociation on the single-atom Pd sites and H spillover from these sites onto the Au host are rate-limiting and key in steering the selectivity of dilute Pd-in-Au alloys toward the hexene isomers. The mechanistic insights from this study contribute to the rational design of optimized dilute alloy catalysts for selective alkene isomerization. This study involved multiple reactions and reactants, such as Sodium tetrachloropalladate(II) (cas: 13820-53-6Application In Synthesis of Sodium tetrachloropalladate(II)).

Green synthesis of microspherical-confined nano-Pd/In₂O₃ integrated with H-ZSM-5 as bifunctional catalyst for CO₂ hydrogenation into dimethyl ether: A carbonized alginate templating strategy was written by Tan, Kok Bing;Tian, Pan;Zhang, Xinxin;Tian, Jian;Zhan, Guowu;Huang, Jiale;Li, Qingbiao. And the article was included in Separation and Purification Technology in 2022.HPLC of Formula: 13820-53-6 The following contents are mentioned in the article:

The present study developed bifunctional catalyst for CO₂ hydrogenation into di-Me ether (DME), whereby it consists of Pd/In₂O₃ for CO₂ hydrogenation into methanol, and H-ZSM-5 for methanol dehydration into DME. The catalyst development was focused on the synthesis of Pd/In₂O₃ via a green and low-cost synthesis method of carbonized alginate templating. Thus, microspherical-confined nano-Pd/In₂O₃ was formed, whereby the localized nucleation growth was coordinated by the chem. entrapped In³⁺ via ionic bond in the well-distributed alginate structure. It was found that hydrothermal temperature plays a key role in the development of this catalyst structure. The optimum hydrothermal temperature is 160°C, as it is able to produce the highest amount of methanol. This catalyst was further integrated with H-ZSM-5 via different integration manners. It was found that mortar mixed method produces the highest amount of DME, as the close proximity causes stronger ion-exchange mechanism between the catalyst components, which facilitates higher oxygen vacancy d. in the bifunctional catalyst. Under the optimum Pd/In₂O₃: H-ZSM-5 (PdIn-160-12: H-ZSM-5) mass ratio of 4:1, the highest STY_DME of 79.7 g_DME kg^-1_cat h^-1 with CO₂ conversion of 9% and DME selectivity of 44.1% can be achieved. In addition, the STY_DME can be maintained even in 60 h on stream, demonstrating the excellent stability and performance of microspherical-confined nano-Pd/In₂O₃/H-ZSM-5 bifunctional catalyst synthesized via carbonized alginate templating strategy.

Second-generation chiral-substituted poly-N-vinylpyrrolidinones (CSPVPs) (-)-1R and (+)-1S were synthesized by free-radical polymerization of (3aR,6aR)- and (3aS,6aS)-5-ethenyl-tetrahydro-2,2-dimethyl-4H-1,3-dioxolo[4,5-c]pyrrol-4-one, (I and II, resp.), using thermal and photochem. reactions. They were produced from resp. D-isoascorbic acid and D-ribose. In addition, chiral polymer (-)-2 was also synthesized from the polymerization of (S)-3-(methoxymethoxy)-1-vinylpyrrolidin-2-one (III). Mol. weights of these chiral polymers were measured using HRMS, and the polymer chain tacticity was studied using ¹³C NMR spectroscopy. Chiral polymers (-)-1R, (+)-1S, and (-)-2 along with poly-N-vinylpyrrolidinone (PVP, MW 40K) were sep. used in the stabilization of Cu/Au or Pd/Au nanoclusters. CD spectra of the bimetallic nanoclusters stabilized by (-)-1R and (+)-1S showed close to mirror-imaged CD absorption bands at wavelengths 200-300 nm, revealing that bimetallic nanoclusters’ chiroptical responses are derived from chiral polymer-encapsulated nanomaterials. Chemo-, regio-, and stereo-selectivity was found in the catalytic C-H group oxidation reactions of complex bioactive natural products, such as ambroxide, menthofuran, boldine, estrone, dehydroabietylamine, 9-allogibberic acid, and sclareolide, and substituted adamantane mols., when catalyst Cu/Au (3:1) or Pd/Au (3:1) stabilized by CSPVPs or PVP and oxidant H₂O₂ or t-BuOOH were applied. Oxidation of (+)-boldine N-oxide 23 using NMO as an oxidant yielded 4,5-dehydroboldine 27, and oxidation of (-)-9-allogibberic acid yielded C6,15 lactone 47 and C6-ketone 48.

Photo-thermo catalytic selective oxidation of cyclohexane by In-situ prepared nonstoichiometric Molybdenum oxide and Silver-palladium alloy composite was written by Wang, Xiaoyu;Feng, Xuyang;Liu, Jincheng;Huang, Zhilin;Zong, Shuang;Liu, Linlin;Liu, Jiarong;Fang, Yanxiong.

The highly selective oxidation of cyclohexane to cyclohexanone and cyclohexanol (KA oil) is one of the most challenging issues in the chem. industry. However, the difficulty in attaining high selectivity and high conversion rate in parallel for the existing catalysts limits its practical application. In this paper, a novel photo-thermo synergistic catalyst was reported for the aerobic oxidation of cyclohexane. The uniform blue MoO_3-x nanowires with small diameter stabilized by polyvinyl pyrrolidone (PVP) were synthesized by a hydrothermal method, and a series of MoO_3-x-AgPd composite materials of different proportions were prepared by an in-situ reduction process. The morphol., crystalline structure, surface chem. bonding, photoelectrochem. properties of MoO_3-x-AgPd composites are thoroughly characterized. The MoO_3-x-AgPd composites present significantly increased catalytic performance than MoO_3-x nanowires in the photo-thermo synergistic catalytic oxidation of cyclohexane under dry air. The high conversion rate of 11.3% with the KA oil selectivity of 99.0% was achieved by the MoO_3-x-Ag₂₀Pd₂₀ composites under photo-thermo catalytic process at 120 °C, which is 1.5 times of that by MoO_3-x nanowires. Under photo-thermo catalytic process, a high cyclohexane conversion rate similar to that of higher temperature thermal catalysis can be obtained at lower reaction temperature, and more cyclohexanol can be produced with a ketone to alc. (K/A) ratio of 0.254. The significantly enhanced catalytic activity can be attributed to the effective charge transfer in the AgPd alloy nanoparticles, the optimized band gap structure, the suppressed charge recombination, and the promoted photo-thermo synergetic catalytic effect. This work provides a new reference scheme for the design and preparation of high-efficiency photo-thermo catalysts for the selective oxidation of cyclohexane.
