In this study, maleic anhydride-acylated chitosan (MAAC) was synthesized by modifying chitosan with maleic anhydride, and used to support palladium catalysts. N-maleyl chitosan-supported palladium (Pd/MAAC) was used as a heterogeneous catalyst for the Heck coupling reaction and reduction of 4-nitrophenol (4-NP). The chem. structure of Pd/MAAC was characterized using FT-IR XPS, XRD, XPS, TEM, SEM/EDS, N₂-physisorption (adsorption-desorption), and ICP-MS. The as-synthesized catalyst exhibited high catalytic performance and could be reused up to nine runs to catalyze the cyclic reaction between iodobenzene and Bu acrylate with low leaching of palladium. Pd/MAAC was also used for the reduction of 4-NP to 4-aminophenol(4-AP) in 90 s at room temperature, and could be reused six times. The findings establish that Pd/MAAC catalyst is an efficient, economical, practical, and environment-friendly catalyst for the Heck reaction and reduction of 4-NP.

Base-free Oxidative Esterification of HMF over AuPd/nNiO-TiO₂. When Alloying Effects and Metal-support Interactions Converge in Producing Effective and Stable Catalysts was written by Campisi, Sebastiano;Bellomi, Silvio;Chinchilla, Lidia E.;Prati, Laura;Villa, Alberto. And the article was included in ChemCatChem in 2022.Category: chlorides-buliding-blocks The following contents are mentioned in the article:

Furan-2,5-dimethylcarboxylate (FDMC), along with ethylene glycol (EG), is the key monomer to produce (poly-(ethylene-furanoate) (PEF). Noble metal-based catalysts can convert hydroxymethyl furfural (HMF) to FDMC in methanol through liquid phase catalytic oxidative esterification. In this work, the catalytic performance of Au, Pd and AuPd NPs supported on nanosized nickel oxide (nNiO) have been evaluated under base-free conditions at 90 °C and 3 bar O2. Synergistic effects between Au and Pd imparted high activity and higher yield to FDMC compared to the monometallic counterparts. The role of support was also investigated by depositing AuPd NPs on TiO₂ and nNiO-TiO₂. Remarkable yield to FDMC (85 % after 8 h) and high stability were observed over AuPd/ nNiO-TiO₂ catalyst. This peculiar catalytic behavior could be imputed to the formation of trimetallic AuPdNi particles offering highly active interfacial sites. This study involved multiple reactions and reactants, such as Sodium tetrachloropalladate(II) (cas: 13820-53-6Category: chlorides-buliding-blocks).

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.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.

And the article was included in Nano Letters in 2022.COA of Formula: Cl4Na2Pd The following contents are mentioned in the article:

New nanostructures often reflect new and exciting properties. Here, we present an two-dimensional, hitherto unreported PdO square network with lateral dimensions up to hundreds of nanometers growing on reduced graphene oxide (rGO), forming a hybrid nanofilm. An intermediate state of dissolved Pd(0) in the bacterium S. oneidensis MR-1 is pivotal in the biosynthesis and inspires an abiotic synthesis. The PdO network shows a lattice spacing of 0.5 nm and a thickness of 1.8 nm on both sides of an rGO layer and is proposed to be cubic or tetragonal crystal, as confirmed by structural simulations. A 2D silver oxide analog with a similar structure is also obtained using an analogous abiotic synthesis. Our study thus opens a simple route to a whole new class of 2D metal oxides on rGO as promising candidates for graphene superlattices with unexplored properties and potential applications for example in electronics, sensing, and energy conversion.

Organic getters are often introduced into sealed systems to remove the excessive reactive hydrogen gas. In this work, the formable graphene aerogel hydrogen getters are prepared by integrating the alkyne-containing mols.(e.g., DEB) into the palladium-loaded three-dimensional layered porous graphene aerogel (Pd-GA). The performance of Pd-GA/DEB composite materials in reducing reactive hydrogen gas is examined at pressures of 0.1-1 bar at a temperature of 25°C, and the hydrogen consumption is measured as a function of time.

In this work, a novel “foaming” strategy uses sodium bicarbonate (NaHCO₃) and ammonium oxalate ((NH₄)₂C₂O₄) as the foaming agent, turning biomass-derived CM-cellulose (CMC) into N-doped porous carbon. Highly active palladium nanoparticles (Pd NPs) immobilized on nitrogen-doped porous carbon (Pd@MC(2)-P) are produced through a phosphate-mediation approach. The phosphoric acid (H₃PO₄) becomes the key to the synthesis of highly dispersed ultrafine Pd NPs on active Pd-cluster-edge (the edge of the Pd-cluster-100 and Pd-cluster-111 surfaces). The Pd@MC(2)-P exhibits high activity for formic acid (FA) dehydrogenation with an initial TOF_g of 971 h^-1 at room temperature The subsequent hydrogenation of phenol using FA as an in situ hydrogen source on Pd@MC(2)-P and the highly efficient hydrogenation of phenol to cyclohexanone reaches more than 90% selectivity and 80% conversion. D. functional theory (DFT) calculations reveal that the reduced H poisoning and more exposed (100) surface over Pd nanoparticles are the keys to the Pd nanoparticles’ high activity.

Thermodynamically favorable oxidation reaction instead of oxygen evolution reaction (OER) with sluggish kinetics as anode reaction and coupled with hydrogen evolution reaction (HER) at cathode is an effective hydrogen production technol. Herein, we report a solvothermal method synthesis of defect-rich crimped perforated PdIn bimetallene as an efficient catalyst for hydrogen production with the assistance of methanol. Boosted by abundant crystal defects, higher surface energy and expanded surface active sites, the defect-rich crimped perforated PdIn bimetallene exhibits superior activity and stability in catalyzing methanol oxidation reaction (MOR) and HER. At the established MOR-HER co-electrolytic system, when the anode and cathode are equipped with PdIn bimetallene, the required cell voltage only is 1.26 V to achieve the c.d. of 100 mA cm^-2, which is 0.93 V lower than that of traditional water electrolysis. This work reports a defect-rich crimped perforated PdIn bimetallene catalyst, as an effective bifunctional catalyst that provides insight for the advancement of energy-saving and promising hydrogen production engineering.

Tuning the electronic properties of single atom catalysts (SACs) between the central metal and the neighboring surface atoms has emerged as an efficient strategy to boost catalytic efficiency and metal utilization. Here we describe a simple and efficient approach to create atomically dispersed palladium atoms supported over defect-contg porous ceria nanorod contg palladium up to 0.26 weight The existence of singly dispersed palladium atoms is confirmed by spherical aberration correction electron microscopy and extended X-ray absorption fine structure measurements. This catalyst shows excellent efficiency in hydrodehalogenation reactions at low H₂ pressure under mild conditions, along with satisfactory recyclability and scalability.

The hydrogen absorption and diffusion processes in cube-shaped palladium (Pd) nanoparticles (NPs) were studied by the combination of ambient-pressure XPS (AP-XPS) and d. functional theory (DFT) calculations A size dependence of the subsurface hydrogen absorption was observed More hydrogen atoms were absorbed in the subsurface of the smaller-sized Pd NPs owing to the enhancement of the diffusivity of H atoms from the surface into the subsurface rather than the adsorption or absorption rates at the initial stages. This results from the weakened Pd-H bond caused by surface disordering of Pd NPs with the reduction of the size of the particles. Furthermore, we discuss the H absorption sites in the bulk by comparing the relative Pd 3d core-level binding energy shifts of the Pd atoms obtained from the AP-XPS results and the theor. calculations The octahedral (O) sites are shown to be more favorable than the tetrahedral (T) sites for hydrogen occupation by comparing the exptl. results and theor. calculations Finally, we proposed an interaction model between hydrogen and the Pd NPs during H2 absorption and diffusion to provide new insights into the hydrogen absorption process.
