Abstract

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 the assistance of citric acid, the MoP@C@rGO composite containing ultrafine MoP nanoparticles with a size of 3 nm anchored on two-dimensional C/rGO nanosheets has been obtained. The chelation effect with citric acid and the merits of rGO not only lead to affordable active sites but also improved the electrical conductivity and stability at the same time. Serving as the hydrogen evolution reaction (HER) electrocatalyst, the MoP@C@rGO composite presents a small overpotential of 168.9 mV at 10 mA cm^-2. It has superior durability when compared to samples of pure MoP, MoP@C, and MoP@rGO. The relative high activity and stable performance as well as the simple preparation process make the MoP@C@rGO composite a promising HER electrocatalyst.
