Summary: Carbon dioxide cycloaddition into fine chemicals is a promising technology for solving energy crisis and environmental issues. This study investigates the effects of metal type on the performance of CO2 cycloaddition using isostructural MOF-919-Cu-Fe and MOF-919-Cu-Al as models. The results reveal that MOF-919-Cu-Fe with exposed Fe and Cu Lewis acid sites exhibits significantly higher conversion and selectivity compared to MOF-919-Cu-Al. The mechanism suggests that the exposed Fe3+ sites facilitate the ring opening of epoxide and CO2 activation, promoting the CO2 cycloaddition reaction.

Summary: A series of zinc complexes with tetradentate aminopyridine ligands were synthesized and characterized. These zinc catalysts were able to couple CO2 with epoxides in excellent yields and broad substrate scope under solvent- and cocatalyst-free conditions. The catalysts could be easily recovered and reused without significant loss in catalytic activity. Catalyst Zn-3 was found to be multifunctional due to a Lewis acidic zinc center, a nucleophilic halide anion, and the release of a pyridine molecule for CO2 activation.

Summary: Earth-abundant metals have become increasingly important in homogeneous catalysis, particularly in the hydroboration reactions of challenging substrates like nitriles, carbonates, and esters. The use of manganese(II) triflate salt in combination with potassium tert-butoxide and pinacolborane enables efficient hydroboration of these substrates with near quantitative yields in less than three hours at room temperature, showcasing a simple and effective methodology for these transformations. Further studies indicate that other earth-abundant metal triflate salts can also facilitate this reaction, expanding the scope of this catalytic process.

Summary: This work presents a novel strategy for synthesizing shape-dependent alloy nanostructures with solid substrates, resulting in significant improvements in electrocatalytic performance. The authors used an aqueous medium approach to synthesize octahedral PdXCuY alloy with different Pd:Cu ratios to better understand their electrocatalytic potential. ZrO2, GONs, and hBNNs solid substrates were used to decorate the optimized Pd3Cu7 catalyst, leading to enhanced hydrogen evolution reaction (HER) activity. The Pd3Cu7@hBNNs catalyst exhibited the lowest overpotential and Tafel values, indicating its excellent performance. Density functional theory calculations further supported the superior performance of Pd3Cu7@hBNNs in achieving the Volmer-Heyrovsky mechanism path.
