And the article was included in Journal of the Iranian Chemical Society in 2022.Application of 13820-53-6 The following contents are mentioned in the article:

PdAu bimetallic nanoparticles synthesized by bacterial cells (Bio-PdAu NPs) are receiving more and more research interest. However, its practical application is extremely limited because of the inefficient PdAu immobilization, which is critical regarding both security and process costs. This work reported one-pot biosynthesis of reduced graphene oxide (rGO)-supported PdAu NPs (Bio-PdAu@rGO) with the Shewanella oneidensis MR-1 at ambient temperature Shewanella oneidensis MR-1 can efficiently reduce GO to rGO and produce face-centered-cubic (fcc) structural PdAu alloy NPs that uniformly embedded on bacterium and rGO. Interestingly, in situ bio-synthesized rGO significantly increased the recovery rate of PdAu NPs from 35.6% to 93.5%. Bio-PdAu@rGO displayed an efficient catalytic activity for Suzuki-Miyaura cross-coupling reactions in contrast to that as-synthesized monometallic bio-Pd NPs, with Bio-PdAu NPs significantly outperforming both. Modest to excellent conversion with 82-100% was obtained when aryl iodide and aryl bromide were used to evaluate the catalytic performance. Moreover, the catalysts had strong universality and tolerate a wide range of substituents. In summary, the small size and uniform size distribution of PdAu NPs, combined with the strong electrostatic attraction and elec. conductivity of rGO, can make Bio-PdAu@rGO an active and stable catalyst in the Suzuki-Miyaura coupling reaction.

No Annealing Synthesis of Ordered Intermetallic PdCu Nanocatalysts for Boosting Formic Acid Oxidation was written by Li, Xiang;Liu, Yaming;Zhang, Jun-Jun;Yan, Bo;Jin, Changqing;Dou, Jingjing;Li, Mengyang;Feng, Xiaohua;Liu, Ge. And the article was included in Chemistry of Materials in 2022.Quality Control of Sodium tetrachloropalladate(II) The following contents are mentioned in the article:

Owing to their high catalytic efficiency and selectivity, the ordered intermetallic Pd-based nanocatalysts have greater promise than disordered nanocatalysts for formic acid oxidation reactions (FAOR). Traditionally, intermetallic nanoparticles are synthesized via the annealing of disordered alloy in a high temperature and reducing atm. However, this method inevitably adds complexity and increases cost to practical application as well as leads to the destruction of nanostructures and the deactivation of nanocatalysts. Herein, monodisperse ordered intermetallic PdCu nanocatalysts are obtained through liquid phase reduction reaction in one pot without heat treatment. The results indicate that the ethylene glycol and KBr not only affect the solubilities of Pd and Cu precursors, but also facilitate the formation of the ordered intermetallic PdCu nanostructures with well-defined morphol. Compared to disordered PdCu, com. Pd/C, and com. Pd black nanocatalysts, the ordered intermetallic PdCu nanocatalysts display enhanced activity and durability for FAOR. The mass and specific activities are 665 mA mg_Pd^-1 and 1.88 mA cm^-2, which are 1.45, 2.67, and 4.16 and 1.21, 1.53, and 1.74 times disordered PdCu, com. Pd/C, and com. Pd black nanocatalysts, resp. This work comes up with one novel approach for the preparation of ordered intermetallic PdCu nanocrystals without heat treatment.

Role of surface steps in activation of surface oxygen sites on Ir nanocrystals for oxygen evolution reaction in acidic media was written by Kim, Myeongjin;Park, Jinho;Wang, Maoyu;Wang, Qingxiao;Kim, Moon J.;Kim, Jin Young;Cho, Hyun-Seok;Kim, Chang-Hee;Feng, Zhenxing;Kim, Byung-Hyun;Lee, Seung Woo. And the article was included in Applied Catalysis, B: Environmental in 2022.Recommanded Product: Sodium tetrachloropalladate(II) The following contents are mentioned in the article:

Ir and its oxide are the only available oxygen evolution reaction (OER) electrocatalysts with reasonably high activity and stability for com. proton-exchange membrane electrolyzers. However, the establishment of structure-performance relationships for the design of better Ir-based electrocatalysts is hindered by their uncontrolled surface reconstruction during OER in acidic media. Herein, we monitor the structural evolution of two model Ir nanocrystals (one with a flat surface enclosed by (100) facets and the other with a concave surface containing numerous high-index planes) under acidic OER conditions. Operando X-ray absorption spectroscopy measurements reveal that the promotion of surface IrO_x formation during the OER by the concave Ir surface with high-index planes results in a gradual OER activity increase, while a decrease in activity and limited oxide formation are observed for the flat Ir surface. After the activation process, the Ir concave surface exhibits ∼ 10 times higher activity than the flat surface. D. functional theory computations reveal that Ir high-index surfaces are thermodynamically preferred for the adsorption of oxygen atoms and the formation of surface oxides under OER conditions. Thus, our work establishes a structure-performance relationship for Ir nanocrystals under operating conditions, providing new principles for the design of nanoscale OER electrocatalysts.

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. This gives them a high tenancy to accumulate in the food chain (biomagnification).Recommanded Product: Sodium tetrachloropalladate(II)

Robust hydrogen production from HCOOH over amino-modified KIT-6-confined PdIr alloy nanoparticles was written by Peng, Wenfang;Liu, Shiwen;Li, Xiugang;Feng, Gang;Xia, Jianhui;Lu, Zhang-Hui. And the article was included in Chinese Chemical Letters in 2022.COA of Formula: Cl4Na2Pd The following contents are mentioned in the article:

Formic acid (FA), which can be produced via CO₂ reduction and biomass conversion, has received extensive interest as a convenient and safe hydrogen carrier due to its wide range of sources, renewable, high hydrogen content (4.4 wt%), and convenient storage/transportation. Designing highly efficient catalysts is the main challenge to realize the hydrogen production from FA. In this work, well-dispersed and electron-rich PdIr alloy nanoparticles with a size of 1.8 nm are confined in amino-modified 3D mesoporous silica KIT-6 and applied as a highly efficient catalyst for robust hydrogen production from FA at ambient temperature Small PdIr alloy nanoparticles confined by amino-modified KIT-6 (PdIr/KIT-6-NH₂) lead to better catalytic activity compared to that of Pd/KIT-6-NH₂ and PdIr confined by bare KIT-6, achieving a high turnover frequency (TOF) value of 3533 h^-1 at ambient temperature (303 K), 100% H₂ selectivity and conversion toward the dehydrogenation of FA, which is comparable to the best heterogeneous catalysts ever reported. The high catalytic activity of PdIr/KIT-6-NH₂ can be attributed to the synergistic effect between Pd and Ir, strong interaction between PdIr and KIT-6-NH₂, as well as the amino-groups of KIT-6-NH₂ which can act as a proton scavenger to promote the breaking of O-H bond of formic acid. This study involved multiple reactions and reactants, such as Sodium tetrachloropalladate(II) (cas: 13820-53-6COA of Formula: Cl4Na2Pd).

Pd/Ni-Al hydrotalcite for base-free alcohol oxidation: Dependency of activity and selectivity on palladium precursors and reduction reagents was written by Dai, Rongrong;Guo, Zheng. And the article was included in Molecular Catalysis in 2022.Computed Properties of Cl4Na2Pd The following contents are mentioned in the article:

Benzyl alc. was chosen as a model substrate for Pd/hydrotalcite mediated selective oxidation of alcs. to investigate the roles of palladium precursors (Na₂PdCl₄, K₂PdCl₄, PdCl₂), reduction reagents (N₂H₄ and NaBH₄), and Pd loading amount in determining structure-activity relationship of flower-like nano-catalyst. XRD analyses show typical characteristic peaks of all hydrotalcites regardless of palladium precursors; whereas TEM studies show a larger mean size of Pd nanoparticles obtained with reducing reagent N₂H₄ over NaBH₄. However, the difference in particle sizes didn’t result in a significant difference in benzyl alc. conversion, but extended to catalytic selectivity where N₂H₄-reduced Pd/hydrotalcite achieved 94%-96% selectivity over 88%-93% by NaBH₄. FTIR-CD₃CN surface acidity study suggested that a stronger acidity of N₂H₄ reduced Pd/hydrotalcite may account for its better selectivity. 3% Pd/hydrotalcite with N₂H₄ as reducing reagent demonstrated the best catalytic performance; and was successfully extended to oxidation of 17 aromatic and aliphatic alcs. The conversion of alcs. is strongly dependent on individual alc. mol. structure and electronic effect; but all reactions showed medium-to-excellent selectivity. This study involved multiple reactions and reactants, such as Sodium tetrachloropalladate(II) (cas: 13820-53-6Computed Properties of Cl4Na2Pd).

Sodium tetrachloropalladate(II) (cas: 13820-53-6) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen.

We report a facile microwave-assisted synthesis of palladium nanoparticles (PdNPs) using Bael gum (BG) and its carboxymethylated (CMBG) derivative The prepared nanoparticles (BG@PdNPs and CMBG@PdNPs) were evaluated for antibacterial and catalytic activity in the reduction of organic dye pollutants. The developed synthetic method is simple, low cost and eco-friendly, wherein the process requires no addnl. reducing or capping agents. The CMBG was prepared via etherification reaction between BG and monochloroacetic acid using Williamson synthesis method. The PdNPs were synthesized using BG and CMBG as stabilizers and reducing agents. The PdNPs were found to be well dispersed spherical, with the crystalline size of the order of 7-21 nm. The results showed that the CMBG@PdNPs were smaller in size (7 ± 2 nm) than those capped with BG@PdNPs (10 ± 2 nm). The catalytic ability of CMBG@PdNPs was examined for the reduction of Methyl orange (MO), Methyl red(MR), and Rhodamine-B (RhB) in the presence of NaBH4. The results showed that CMBG@PdNPs exhibited a higher catalytic ability than BG@PdNPs. Moreover, it was found that CMBG@PdNPs served several times as a retrievable and reusable catalyst which is stable even after six cycles of reaction. The CMBG@PdNPs and BG@PdNPs showed excellent antibacterial activity. The results indicate that CMBG@PdNPs have greater potential application as a catalyst in the reduction of organic pollutants and antibacterial activity.

Size Sensitivity of Supported Palladium Species on Layered Double Hydroxides for the Electro-oxidation Dehydrogenation of Hydrazine: From Nanoparticles to Nanoclusters and Single Atoms was written by Liu, Guihao;Nie, Tianqi;Wang, Huijuan;Shen, Tianyang;Sun, Xiaoliang;Bai, Sha;Zheng, Lirong;Song, Yu-Fei. And the article was included in ACS Catalysis in 2022.Reference of 13820-53-6 The following contents are mentioned in the article:

The hydrazine oxidation reaction (HzOR) is structure-sensitive, and a slight modification of the catalyst structure can generate a significant change in activity. To date, no study on the size effect of the catalyst at a subnanometer scale on HzOR is reported yet. Herein, the authors report the fabrication of Pd species with sizes ranging from nanoparticles (NPs) and nanoclusters (NCs) to single atoms (SAs) onto a NiFe-layered double hydroxide by fine-tuning precursors and reduction methods. When applied for the electrooxidation dehydrogenation of hydrazine, the as-prepared Pd NCs/NiFe exhibit a c.d. of 4.3 A mg_Pd^-1 at 0.35 V vs. RHE. It should be noted that the mass activity of Pd NCs/NiFe was 36 times that of Pd SAs/NiFe and 7 times that of Pd NPs/NiFe, resp. The in situ electrochem. impedance spectroscopy and d. functional theory calculation demonstrate that different from previous studies, both the Pd SAs/NiFe and Pd NPs/NiFe are suboptimal in HzOR due to the isolated active sites of the Pd SAs/NiFe and large steric hindrance of Pd NPs/NiFe, resp. Instead, the strong intracluster interactions of Pd NCs/NiFe lift the d-band center closer to the Fermi level, leading to stronger hybridization of Pd d-orbitals and the σ orbitals of N₂H₄ mols. Consequently, the excellent performance of Pd NCs/NiFe can be attributed to its multiple neighboring metal sites, high d-band center, and small steric hindrance. This study involved multiple reactions and reactants, such as Sodium tetrachloropalladate(II) (cas: 13820-53-6Reference of 13820-53-6).

Lamellar and Conductive Ion Associations Advance the Electrochemical Catalytic Performance of Palladium was written by Shi, Jingling;Li, Mengqian;Zheng, Yunshan;Ying, Ye;Guo, Xiaoyu;Wu, Yiping;Liu, Xinling;Wen, Ying;Yang, Haifeng. And the article was included in ACS Applied Energy Materials in 2022.Synthetic Route of Cl4Na2Pd The following contents are mentioned in the article:

Engineering non-Pt electrocatalysts that are accompanied with superior activity and durability toward MeOH oxidation reaction (MOR) remains a great challenge. A lamellar and conductive ion association is easily formed by mixing Na₂PdCl₄, (NH₄)₆Mo₇O₂₄, and cetyltrimethylammonium bromide (CTAB), designated as PdMoCTAB. Through tuning the amounts of precursors, three kinds of Pd supported by lamellar ion association are fabricated by a facile hydrothermal method. Surprisingly, when the at. ratio of Pd and Mo is 1.8:1, the resultant Pd/PdMoCTAB (denoted as Pd_1.8Mo) presents great catalytic performance for MOR in an alk. medium with a high peak c.d. of 2178 mA mg_metal^-1. The mechanism could be due to the high loading efficiency of Pd on the great surface of ion association, rapid mass transferring in the lamellar structure, and abundant strain defects of Pd induced by the deformation of ion association as well as the good conductivity of PdMoCTAB. Pd_1.8Mo also shows improved stability, whereby the c.d. maintains 104 mA mg_metal^-1 after electrochem. catalysis for 10,000 s and, after 500 cycles, the mass activity retains ∼64% of the initial value. Such conductive and lamellar PdMoCTAB ion association is expected to become a promising support to load various noble metals for preparing excellent electrochem. catalysts.

Heart failure (HF) is a major public health problem trigged by a heart circulation disorder. Early detection and diagnosis are conducive to the prevention and treatment of HF. N-terminal B-type natriuretic peptide precursor (NT-proBNP) is considered to be a sensitive diagnostic biomarker of HF. In this study, we constructed a NT-proBNP sandwich electrochem. immunosensor by using electroplated gold nanoparticles (Au NPs) as the substrate and utilizing rough-surfaced trimetallic Au@PdPt nanozymes (Au@PdPt RTNs) as current signal amplification. The Au NPs as substrate material modified glassy carbon electrode (GCE) have excellent conductivity and biocompatibility, which not only accelerate electron transfer rate, but also improve the loading capacity of primary antibody (Ab1). Moreover, the Au@PdPt RTNs were synthesized by a one-pot method and used as the labels to bound with secondary antibodies (Ab2) via the Pt-N. The large sp. surface area and excellent catalytic properties for H2O2 of Au@PdPt RTNs can effectively enhance the stability and sensitivity of the immunosensor. With the favorable cooperation of Au NPs and Au@PdPt RTNs, the constructed immunosensor exhibited a wide concentration range from 0.1 pg mL-1 to 100 ng mL-1 and a low detection limit of 0.046 pg mL-1. Furthermore, the accuracy of the anal. of NT-proBNP in diluted human serum samples was satisfactory. The results revealed the electrochem. immunosensor has a prospective application in clin. detection.

Direct formic acid fuel cells (DFAFCs) are promising power generation technologies for various electronic devices. The design of efficient and stable electrocatalysts for the formic acid oxidation reaction (FAOR) plays an important role for the com. applications of the DFAFCs. Herein, porous boron nitride (BN) supported Pd nanoparticles (NPs) have been developed as unique and effective composite catalysts for FAOR. Porous BN nanofibers (BNNFs) has been utilized as a functional support to anchor of Pd NPs. The high sp. surface area and rich porosity of BNNFs play a key role for the well-dispersion and stabilization of Pd NPs with uniform ultra-small size (∼2.32 nm) on their surface. The developed Pd/BNNFs composite catalyst exhibits excellent catalytic activity for FAOR with the mass activity of 725 mA mg^-1Pd and a very low onset potential (about -0.12 V). Comparative experiments confirm that the microstructure of porous BN carrier greatly affects the electrocatalytic behaviors of the composite catalyst in FAOR. As compared with the composite catalyst using BN microfibers (BNMFs) as a support, the developed Pd/BNNFs catalyst shows superior catalytic activity and long-term stability owing to the larger sp. surface area of BNNFs and stronger interaction between Pd NPs and support. This study not only illustrates that porous BN is a desirable catalyst carrier for catalytic FAOR but also provides new ideas for the design of novel BN-based catalysts.
