Summary: In this study, a nanostructured iridium catalyst supported on NiO (IrNP@NiO) was introduced for acceptorless dehydrogenative oxidation of primary alcohols. The catalyst was synthesized using a simple wet chemical technique and characterized by various analyses. The catalyst showed high selectivity in converting primary alcohols to acids or carboxylates under the presence of a base, and aldehydes were obtained under base-free conditions. The catalyst also demonstrated efficient conversion of biomass-based alcohols, and could be easily separated and reused multiple times.

Summary: Iridium(I) compounds with bridge-functionalized bis-NHC ligands were prepared and showed high activity and selectivity in the oxidative dehydrogenation of glycerol to lactate. The hydroxy-functionalized bis-NHC catalysts were more active than the carboxylate-functionalized ones and the unbridged bis-NHC iridium(I) catalyst.

Summary: The acceptorless dehydrogenation of methanol to carbon monoxide and hydrogen using homogeneous molecular complexes, particularly those containing ruthenium and manganese with the MACHO ligand framework, showed promising catalytic activities. The metal complex was found to mediate the initial fast dehydrogenation of methanol to formaldehyde and methyl formate followed by subsequent slow decarbonylation, resulting in gas mixtures with varying CO/H2 ratios.

Summary: Co-Ru bimetallic nanoparticles were synthesized by co-reduction of Co(II) and Ru(III) salts using octan-1-ol as a solvent and mild reducing agent. The formation of stable nanoalloys required careful selection of reaction parameters and metal precursors. The particles with higher Ru content exhibited smaller size and better size dispersity. The bimetallic particles showed improved performance compared to their monometallic counterparts in acceptorless alcohol dehydrogenation.

Summary: This study reports a Pd-catalyzed deoxygenative coupling of heptanol with heterogeneous catalysts composed of Pd immobilized on acid-base supports, primarily including basic MgO, acidic gamma-Al2O3, and Mg-Al hydrotalcite (HT). The results show that Pd-HTs with 1% and 5 wt % Pd loading afford the highest overall activity, yielding 30% hydrocarbons from heptanol. The impact of support selection on the activity and selectivity provides insights for designing next-generation catalysts for this process and related transformations.

Summary: A novel porous organic polymer-supported single-site nickel catalyst with large surface area was synthesized and proved to have excellent catalytic activity in the one-pot synthesis of poly-substituted pyrimidine derivatives. Mechanistic explorations revealed that the transformation involves acceptorless dehydrogenation, metal-mediated Michael reaction, and 1,5-electrocyclization. The catalyst also showed good stability after eight runs.

Summary: Sulfide compounds show promise as electrocatalysts for water splitting, but their performance is limited by factors such as limited active sites and hindered substance transport. This study successfully prepared a high-entropy sulfide (ZnCoMnFeAlMg)(9)S-8, which reduced grain size and increased specific surface area, enabling the realization of a dual-functional catalyst with multiple catalytic sites. High entropy also modulated the electronic properties of sulfides, reducing the potential energy barrier for hydrolysis. This research introduces a new approach for functionalizing high entropy nanomaterials and improves the performance of water splitting catalysts.
