Electrocatalytic water splitting is a clean and feasible method for hydrogen production, expected to become key technology meeting energy demands. Transition metal-based nanoparticles, including single-atom catalysts their compounds, are widely used in electrocatalytic splitting, but they often suffer from issues like easy agglomeration poor conductivity. The integration of these nanoparticles with three-dimensional (3D) graphene enhances conductivity prevents agglomeration, while improving the adsorption desorption rates reactants intermediates on catalyst surface during thereby boosting efficiency. This paper reviews preparation methods graphene-based supported electrocatalysts applications oxygen evolution reactions (OERs), further discussing mechanism by which 3D improves OER performance.

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.
