Enhanced Oxygen Evolution Reaction Activity of a Co₂P@NC–Fe₂P Composite Boosted by Interfaces Between a N-Doped Carbon Matrix and Fe₂P Microspheres

Constructing highly efficient and low-cost transition-metal-based electrocatalysts with a large number of interfaces to increase their active site densities constitutes a major advancement in the development of water-splitting technology. Herein, a bimetallic phosphide composite (Co2P@NC-Fe2P) is successfully synthesized from a ferric hydroxyphosphate-zeolitic imidazolate framework hybrid precursor (FeHP-ZIF-67). Benefitting from morphology and...
