Abstract Oxygen electrocatalysis is a core reaction in renewable energy devices, greatly promoting the transformation and upgrading of structure. Nonetheless, performance conversion devices hindered by large overpotential slow kinetics oxygen electrocatalytic reactions. Recently, single‐atom catalysts (SACs) have emerged as promising contenders field because their exceptional metal atom utilization, distinctive coordination environment, adjustable electronic properties. This review presents latest advancements design Co‐based SACs for electrocatalysis. First, OER ORR mechanisms are introduced. Subsequently, strategies regulating structure summarized three aspects, including centers, support carriers. A particular emphasis given to relationship between properties catalysts. Afterward, applications explored. Ultimately, challenges prospects prospected.

A highly dispersed bimetallic catalyst, AuRu/ZIF-67, and monometallic catalysts, Au/ZIF-67 Ru/ZIF-67, were successfully prepared herein via co-impregnation/impregnation hydrogen reduction methods. The catalytic performances of the Au-Ru Au Ru catalysts for benzyl alcohol oxidation compared under an O2 atmosphere. Results revealed that addition to catalyst reduced activity while considerably improving yield benzaldehyde. reaction solvent, temperature, pressure time exerted crucial effects on performance AuRu/ZIF-67. optimal conditions when using AuRu/ZIF-67 70℃, 5 bar 4 h with tetrahydrofuran as solvent. conversion benzaldehyde 82.9% 47.5%, respectively, conditions. exhibited excellent applicability towards alcohols; particularly aromatic aliphatic alcohols, where good conversions acceptable yields aldehydes obtained. Moreover, demonstrated stability oxidation, it could be recycled four times without any changes in yield.
