Single-atom catalysts (SACs), featuring high atom utilization, have captured widespread interests in diverse applications. However, the single-atom sites SACs are generally recognized as independent units and interplay of adjacent is largely overlooked. Herein, by direct pyrolysis MOFs assembled with Fe Ni-doped ZnO nanoparticles, a novel Fe1-Ni1-N-C catalyst, neighboring Ni pairs decorated on nitrogen-doped carbon support, has been precisely constructed. Thanks to synergism pairs, presents...
Abstract Rh-based heterogeneous catalysts generally have limited selectivity relative to their homogeneous counterparts in hydroformylation reactions despite of the convenience catalyst separation catalysis. Here, we develop CoO-supported Rh single-atom (Rh/CoO) with remarkable activity and towards propene hydroformylation. By increasing mass loading, isolated atoms switch aggregated clusters different atomicity. During hydroformylation, Rh/CoO achieves optimal 94.4% for butyraldehyde...
Electrochemical reduction of CO2 to multi-carbon fuels and chemical feedstocks is an appealing approach mitigate excessive emissions. However, the reported catalysts always show either a low Faradaic efficiency C2+ product or poor long-term stability.
