Facile synthesis of MoS2/rGO-MOF hybrid material as highly efficient catalyst for hydrogen evolution

MoS2/rGO-MOF hybrid material as a highly effective electrocatalyst for hydrogen evolution reaction (HER) has been synthesized by a two-step hydro- and solvothermal process by loading MoS2 on the surface of copper-centered metal organic framework (Cu-MOF) and graphene oxide (GO) hybrid. The obtained MoS2/rGO-MOF hybrid catalyst exhibits an excellent electrocatalytic HER activity with small onset overpotential of 60 mV and a low Tafel slope of 36 mV decade−1. The enhancement of catalytic activities was ascribed to the higher specific surface area beneficial from the mesoporous structure of GO-MOF hybrid and synergetic effect between MoS2 nanosheets and GO-MOF matrix.
