Abstract
The present application relates to the technical field of catalyst, especially to a surface-reconstructed heterojunction catalyst and its preparation method and application. The present application combines high-temperature atomization deposition and phosphating treatment to build Ga-doped Ni2P / Fe2P heterostructure on a nickel mesh substrate, and in-situ reconstructs to form a NiOOH / FeOOH-Ga2O3 heterojunction catalyst during the OER process. Ga2O3 induces interface electron delocalization through p-d orbital hybridization, optimizes the reaction kinetics, and simultaneously acts as a physical barrier layer to inhibit Cl ‑ corrosion, thereby endowing the catalyst with high activity, high selectivity and high stability.
