As a new generation of non-precious metal catalysts, nickel phosphide is regarded as an ideal substitute for precious metal platinum in electrochemical hydrogen evolution. Here, a hydrogen evolution reaction (HER) electrocatalyst is developed by in situ growth of NiP/NiP heterostructures on porous N decorated rGO foam (named NiP/NiP/N-rGO). The porous rGO foam structure provides a larger surface area and abundant active sites. The NiP/NiP nanoparticles with heterostructures are uniformly distributed on the rGO sheet, which enhance the charge transfer ability. The decorating of N element also correspondingly improves the HER performance. The as-prepared NiP/NiP/N-rGO exhibits excellent HER performance in alkaline medium. When the current density is 10 mA cm, the overpotential is only 22 mV. No obvious loss of HER activity after 2000 cyclic voltammetry indicates that the composite has excellent stability. This work presents a valuable route for fabricating inexpensive and high-performance catalysts for electrocatalysis.
