Mimic enzymes, especially noble metal nanomaterials, replace natural horseradish peroxidase due to the artificial regulation of catalytic activity by adjusting particle size and morphol. However, the existing mimic enzymes still have disadvantages such as large particle size, easy clustering and poor biocompatibility. Herein, well-dispersed daptomycin stabilized palladium nanoparticles (Dap-Pdn NPs) were synthesized by using daptomycin as a biol. template. The average particle size of palladium nanoparticles of Dap-Pd_0.25 NPs was 1.73 nm, the hydrodynamic size of Dap-Pd_0.25 NPs detected by DLS method was 49.97 nm, Dap-Pd_0.25 NPs were stable in fibrinogen solution In addition, Dap-Pd_0.25 NPs had excellent peroxidase-like activity, which effectively catalyzed the colorimetric oxidation reaction of 3,3′,5,5′-tetramethylbenzidine (TMB) by H₂O₂. Dap-Pd_0.25 NPs were used to detect glucose concentration based on the colorimetric reaction of TMB, which had a wide detection range (0.02-1 mM) and low detection limit (5.6μM) for glucose. Besides, fluorescence experiments proved that Dap-Pdn NPs catalyzed H₂O₂ to generate.OH. Taken together, a simple, green and inexpensive synthesis method of palladium nanoparticles with enhanced peroxidase-like activity was proved in this research. Dap-Pdn NPs will have great application prospects in biol. detection in the future.

Stepwise synthesis of “Pt-on-PdAg” hybrid trigonal/hexagonal nanocrystals for efficient electroxidation of methanol: Interface engineering for trimetallic electrocatalyst was written by Zhang, Gongguo;Wang, Yingying;Liu, Feng;Kong, Yuhan;Liu, Maochang;Zheng, Yiqun. And the article was included in Journal of Alloys and Compounds in 2022.Name: Sodium tetrachloropalladate(II) The following contents are mentioned in the article:

We report the fabrication of “Pt-on-PdAg” heterogeneous nanocrystals in the form of trigonal/hexagonal plate (THNPs) and explored their applications in electroxidn. of methanol (MOR) in alk. medium. In particular, PdAg polyhedral nanoparticles are prepared in advance, followed by the addition of Pt salts to allow in situ galvanic replacement reaction (GRR) between them, leading to the formation of Pt nano-islands on PdAg particle surface and the transformation of the overall morphol. into trigon/hexagon. The deliberately designed Pt-“PdAg alloy” interface arising from the hybrid structure greatly enriches the absorption sites, showing noticeable structural advantages in MOR electrocatalysis. Particularly, the carbon-supported Pt-on-PdAg THNPs exhibit nearly 30-fold increase in specific activity as compared to that of com. Pt/C, as well as enhanced reaction kinetics and long-term durability. DFT calculations suggest that the reaction of CH3OH oxidation mediated by PtAgPd is energetically more favorable compared to the similar reaction promoted by Pt, which rationalizes the exptl. observation that PtAgPd shows the improved catalytic performance. The present study offers a feasible route to construct trimetallic nanocrystals with successful interface engineering, and validates their promising use as fuel cell electrocatalyst from both exptl. validation and fundamental insights. It may help enlighten the rational design of heterostructured electrocatalysts with regulated multiple active sites.

Liquid Metal Interfacial Growth and Exfoliation to Form Mesoporous Metallic Nanosheets for Alkaline Methanol Electroreforming was written by Wang, Shengqi;Mao, Qiqi;Ren, Hang;Wang, Wenxin;Wang, Ziqiang;Xu, You;Li, Xiaonian;Wang, Liang;Wang, Hongjing. And the article was included in ACS Nano in 2022.Reference of 13820-53-6 The following contents are mentioned in the article:

Two-dimensional (2D) materials have spurred great interest in the field of catalysis due to their fascinating electronic and thermal transport properties. However, adding uniform mesopores to 2D metallic materials has remained a great challenge owing to the inherent high surface energy. Here, we introduce a generic liquid metal interfacial growth and exfoliation strategy to synthesize a library of penetrating mesoporous metallic nanosheets. The formation of liquid-metal/water interface promotes the adsorption of metal ion-encapsulated copolymer micelles, induces the self-limiting galvanic replacement reaction, and enables the exfoliation of products under mech. agitation. These 2D mesoporous metallic nanosheets with large lateral size, narrow thickness distribution, and uniform perforated structure provide facilitated channels and abundant active sites for catalysis. Typically, the generated mesoporous PtRh nanosheets (mPtRh NSs) exhibit superior electroactivity and durability in hydrogen evolution reaction as well as methanol electrooxidation in alk. media. Moreover, the constructed sym. mPtRh NSs cell requires only a relative low electrolysis voltage to achieve methanol-assisted hydrogen production compared with traditional overall water electrolysis. The work reveals a specific growth pattern of noble metals at the liquid-metal/water interface and thus introduces a versatile strategy to form 2D penetrating mesoporous metallic nanomaterials with extensive high-performance applications.

Correlation of adsorbed and embedded palladium species in chitosan composite nanofibers with their catalytic activities for Suzuki reactions was written by Su, Baogang;Zhang, Qi;Shao, Linjun;Zhou, Shujing;Li, Jinjing;Du, Yijun;Qi, Chenze. And the article was included in Journal of Physics and Chemistry of Solids in 2022.SDS of cas: 13820-53-6 The following contents are mentioned in the article:

Heterogeneous palladium catalysts play an important role in the synthetic organic chem. Palladium species have been adsorbed on the surface of solid matrixes or embedded inside solid matrixes to prepare recyclable heterogeneous catalysts. Due to the different surrounding environment, these two type palladium species had different electronic properties and catalytic performances. In this study, we fabricated three series of chitosan composite nanofibers with adsorbed and embedded palladium species. Their fiber morphologies and chem. structures were characterized by SEM and FT-IR, resp. Positron annihilation lifetime spectra (PALS) showed that the intensities (I3) of o-Ps annihilations were all linearly decreased with the increase of palladium contents in the chitosan composite nanofibers. Moreover, compared with the palladium adsorbed chitosan composite nanofibers, the palladium embedded chitosan composite nanofibers had stronger o-Ps annihilation ability, which could be ascribed to the stronger electron donating property of embedded palladium species and higher crosslinking of chitosan mols. by embedded palladium species. At last, the I3 values were successfully correlated with the rate constants of chitosan supported palladium composite nanofibers catalyzed Suzuki reactions of iodobenzene with phenylboric acid. Therefore, we have developed a facile method to distinguish the adsorbed and embedded palladium species by PALS, which can be further related with their catalytic performance.

And the article was included in ACS Sustainable Chemistry & Engineering in 2022.Related Products of 13820-53-6 The following contents are mentioned in the article:

In this contribution, we have reported our study on the fine-tuned design and synthesis of new POLITAGs-Pd⁰ (POLymeric Ionic TAG) catalytic systems with the intention of defining highly efficient heterogeneous palladium catalysts stabilized by ionic tags able to operate at a very low loading while being fully recoverable/reusable. By varying both the support and the ratio between the metal and immobilized ionic tag, we have accessed five different heterogeneous catalytic systems that have been fully characterized (EA, XPS, TEM, and HR-TEM) to investigate their morphol. differences. The catalytic efficiency of the newly prepared POLITAGs-Pd⁰ materials was then tested and compared in the representative Mizoroki-Heck cross-coupling reaction, a universally investigated and widely useful process. A close correlation between the catalyst support and catalytic performances has been highlighted. The best system POLITAG-Pd⁰-HM features a high TOF value (26,786 h^-1), affording the final products in high isolated yields by using as little as only 0.0007 mol % of Pd. Moreover, this high catalytic activity coupled with the use of γ-valerolactone (GVL) as a green reaction medium has led to the definition of a very efficient waste-minimized protocol. The newly designed catalyst has been utilized in the representative synthesis of Amiloxate, a widely used sunscreen agent, that could be prepared with negligible metal contamination and very low E-factor.

Oxygen Vacancy in CeO₂ Facilitate the Catalytic Activity of Pd/CeO₂ for CO Direct Esterification to Dimethyl Oxalate was written by Hu, Chao;Jing, Kai-Qiang;Lin, Xiao-Qi;Sun, Jing;Xu, Zhong-Ning;Guo, Guo-Cong. And the article was included in Catalysis Letters in 2022.Recommanded Product: Sodium tetrachloropalladate(II) The following contents are mentioned in the article:

CO direct esterification to di-Me oxalate (DMO) has important industrial application value. Pd-based heterogeneous catalysts have been often utilized for this reaction. However, the effects of defect structures causing by the different morphologies of the support on the catalytic performance has not been investigated sufficiently. In this work, three different morphologies of CeO₂ support (denoted as rod, cube, and octahedron) loading Pd were synthesized, and further investigated their catalytic activities for CO direct esterification to DMO. The Pd/CeO₂-rod catalyst exhibited the best CO conversion compared with Pd/CeO₂-cube and Pd/CeO₂-octa. The results of Raman and XPS show that CeO₂-rod has the highest oxygen vacancy concentration than those of CeO₂-cube and CeO₂-octa. In addition, it was found that partial interfacial electrons transfer from Pd to CeO₂ support at the interface from the result of XPS. More intriguingly, the result of in situ DRIRS of CO exhibits that the partial interfacial electrons transfer from CeO₂ to Pd, resulting from oxygen vacancies serve as a charge compensator to promote partial electrons transfer. The enriched electron of Pd would promote the adsorption and activation of CO, thus enhancing the catalytic activity. This work will provide a general understanding of the support effect to catalytic performance, which induced by the oxygen vacancies.

Fast room-temperature hydrogenation of nitroaromatics on Pd nanocrystal-boron cluster/graphene oxide nanosheets was written by Wang, Yuwen;Bi, Zenghui;Zhao, Xue;Abdukayum, Abdukader;Zhou, Shuxing;Zhang, Haibo;Chen, Jianbing;Tan, Fang;Chen, Anran;Wagberg, Thomas;Hu, Guangzhi. And the article was included in Molecular Catalysis in 2022.Synthetic Route of Cl4Na2Pd The following contents are mentioned in the article:

The reduction of nitroaroms. to aminoaroms. is essential for fine chem. production and effective sewage treatment. However, the activity of an external catalyst is essential for the reaction. In this study, Pd nanocrystals were anchored in situ on two-dimensional graphene oxide (GO), which acted as a catalyst support with high sp. surface area. The oxygen-containing groups on the surface of GO bonded to the functionally rich boron clusters through hydrogen bonding interactions. A mildly reducible closed-dodecahydrododecaboric acid anion cluster (closo-[B₁₂H₁₂]^2-) was employed as the target site. The mild reducibility of closo-[B₁₂H₁₂]^2- resulted in a wide dispersion of ultrafine Pd nanocrystals on GO. Under ambient conditions, Pd/BGO rapidly hydrogenated nitroaroms., such as 4-nitrophenol, to aminoaroms. with approx. 100% efficiency. Moreover, Pd/BGO retained its high catalytic activity for the hydrogenation/reduction of 4-nitrophenol after five catalytic cycles. Therefore, Pd/BGO could be a promising and economically viable candidate for various practical applications. The proposed innovative preparation strategy and highly efficient catalytic activity suggested the effective performance of closo-[B₁₂H₁₂]^2- as nanometal nucleation target sites. In addition to providing an alternate route for preparing supported nanometals, this study presents a stable and efficient catalyst for the hydrogenation of nitroaroms.

The construction of nanozymes at the at. level that hold structural stability and high enzyme-like activity is now a key factor in the optimization of an artificial enzyme. Single-atom metal/cerium oxide (CeO₂)-based nanozymes have been demonstrated to possess a variety of enzymic activities and radical scavenging abilities, which are mainly attributed to the single-atom active site, redox valence states, and abundant defect chem. Here, we developed a single-atom Pd/CeO₂ nanostructure by aqueous phase synthesis that exhibits the advantages of high yield and good stability. The Pd/CeO₂ nanostructure possesses peroxidase (POD), superoxide dismutase (SOD), and catalase (CAT) activities as well as reactive nitrogen species free-radical scavenging activity, exhibiting multienzyme-like activities and stability compared with CeO₂ and other metal-based nanozymes. It is worth mentioning that the Pd/CeO₂ nanostructure exhibits high POD-mimicking activity with a reaction rate of 0.88μM/min, about 5 times higher than that of the CeO₂ nanozyme. In addition, the CAT-like activity of the Pd/CeO₂ nanostructure is excellent, and its scavenging rate of hydrogen peroxide reached nearly 100% at a concentration of 50 ng/μL. The present work shows that single-atom Pd substitution is a promising strategy for the design of CeO₂ nanozymes to exert better effects on biomedical applications, especially with diseases related to oxidative stress.

Fast charge separation and transfer strategy in polymeric carbon nitride for efficient photocatalytic H₂ evolution: Coupling surface Schottky junctions and interlayer charge transfer channels was written by Gao, Manyi;Tian, Fenyang;Zhang, Xin;Liu, Yequn;Chen, Zhaoyu;Yu, Yongsheng;Yang, Weiwei;Hou, Yanglong. And the article was included in Nano Energy in 2022.Category: chlorides-buliding-blocks The following contents are mentioned in the article:

Reinforcing the charge separation and transfer in layered polymeric carbon nitride (PCN) is the key issue to enhance its photocatalytic activity but still remains very challenging. Herein, for the first time, the synergetic Pd single atoms (PdSAs) and carbon-supported Pd nanoparticles (NPs) are introduced into the interlayer and surface of layered PCN resp. to address this challenge. The PdSAs are in intimate contact with the adjacent PCN layers and serve as interlayer charge transfer channels, while the carbon-supported Pd NPs contribute to multistep PCN-carbon-Pd NPs Schottky junctions on PCN surface. Experiments and theor. calculations demonstrate that such unique architectures provide intrinsic driving force to extract the electrons from PCN to outermost Pd NPs with high migration rate via vertical PdSAs channels. This directional charge transfer in PCN greatly expedite the separation of charge carriers in both inner and surface of PCN and simultaneously yield electron-rich Pd NPs active sites with optimized H₂ adsorption energy, thus leading to improved intrinsic H2 evolution reaction kinetics. Consequently, the Pd/PCN2 performs ultrahigh photocatalytic H₂ evolution rate of 83.34 mmol g^-1 h^-1 in the dispersed particulate system and 100.4 mmol h^-1 m^-2 in the film form under simulated sunlight. This work provides a new promising approach to engineer the spatial charge transfer behaviors for high-performance PCN-based photocatalysts.

Gold modified thiol graphene (Au@HS-rGO) was prepared and applied as sensing platform for constructing the electrochem. aptasensor. While gold-palladium modified zirconium metal-organic frameworks (AuPd@UiO-67) nanozyme was employed as signal enhancer for detecting mercury ions (Hg²⁺) sensitively. Herein, gold nanoparticles (Au NPs) were modified on HS-rGO to form the thin Au@HS-rGO layer. Then the substrate strand (Apt1) was modified on the platform through Au-S bond. The signal strand (Apt2) was further decorated on the platform in the presence of Hg²⁺. Herein, the Apt2 was labeled with AuPd@UiO-67 nanozyme, which exhibited catalase-like properties to catalyze H₂O₂, thereby generating the elec. signal. With the concentration of Hg²⁺ increased, the amount of modified Apt2-AuPd@UiO-67 increased, leading to the rise of current response. Since the current responses were linear with concentration of Hg²⁺, the detection of Hg²⁺ can be achieved. Under the optimum conditions, the prepared electrochem. aptasensor exhibited wide linear range from 1.0 nmol/L to 1.0 mmol/L, along with a low detection limit of 0.16 nmol/L. Moreover, the electrochem. aptasensor showed excellent selectivity, reproducibility and stability, together with superior performance in actual water sample anal. Therefore, this proposed electrochem. aptasensor may have promising applications and provide references for environmental monitoring and management.
