Electrochemical water-splitting with non-noble metal catalysts provides an eco-friendly strategy for renewable production of hydrogen. In this study, the MoP@C@reduced graphene oxide (rGO) composite was prepared via mild reactions through a chemical bath and postannealing process. With assistance citric acid, MoP@C@rGO containing ultrafine MoP nanoparticles size 3 nm anchored on two-dimensional C/rGO nanosheets has been obtained. The chelation effect acid merits rGO not only lead to affordable active sites but also improved electrical conductivity stability at same time. Serving as hydrogen evolution reaction (HER) electrocatalyst, presents small overpotential 168.9 mV 10 mA cm-2. It superior durability when compared samples pure MoP, MoP@C, MoP@rGO. relative high activity stable performance well simple preparation process make promising HER electrocatalyst.
