Summary: By anchoring Co and Cu sites onto a hierarchical porous N-doped carbon matrix, we designed a diatomic catalyst (Co/Cu-N-C) that exhibits outstanding performance in higher alcohol synthesis. With a CO conversion of 81.7%, it achieves a C(2+)OH selectivity of 58.5% and a remarkable C2+OH STY of 851.8 mg/g center dot h. The N-4-Co-1 and Cu-1-N-4 sites demonstrate excellent synergistic effects, with CO adsorbing on the Co site and surrounding nitrogen sites acting as a hydrogen reservoir for CO reduction reactions to form CHxCo. Simultaneously, the Cu sites stabilize a CHOCu species to interact with CHxCo, promoting barrier-free formation of C-2 species and enhancing the selectivity of higher alcohols.

Summary: A study successfully synthesized different-sized Ru-based catalysts and evaluated their performance for the hydrogen evolution reaction (HER). The results showed that the Ru nanocluster catalyst had the optimal catalytic performance under alkaline, neutral, and acidic conditions. The exceptional performance was attributed to the strong interaction between the Ru nanoclusters and the N-doped carbon support, which weakened the *H adsorption ability of Ru sites.
