Fabrication of MoS2-Decorated Nickel-Cobalt Bimetal Phosphide Nanocubes as Efficient Electrocatalysts for Hydrogen Evolution

摘要

Nickel-cobalt bimetal phosphides were prepared via the phosphidation treatment of NiCo-based Prussian blue analogue (PBA). Subsequently, the core-shell structures of NiCoP@MoS2 were successfully assembled through a solvothermal reaction, where the NiCoP substrates were uniformly and randomly covered by MoS2 nanosheets. The resulting hybrids exhibited significantly superior catalytic activities towards hydrogen evolution reaction (HER) in 0.5 M H2SO4 to bare MoS2.
