Modulating electronic structure of cobalt phosphide porous nanofiber by ruthenium and nickel dual doping for highly-efficiency overall water splitting at high current density

The rational design and construction of high-efficiency bifunctional electrocatalysts are the central challenges for improving the overall water splitting efficiency. In this paper, Ru and Ni dual-metal doped CoP (Ru, Ni–CoP) porous nanofibers were fabricated. Dual-metal doping can be more efficiently used to modulate the electronic structure than single-metal doping, thereby, achieving decreased water dissociation energy and optimized...
