Abstract
A simple wet chemical method has been used to prepare MoSx in situ grown on graphene oxide (MoSx/GO) as a highly active and stable electrocatalyst for hydrogen evolution reaction (HER). The role of the oxygen-containing functional group on the surface of \GO\ with different oxidation degrees have been studied for obtaining MoSx/GO with excellent electrochemical activity for HER. The electrochemical measurements show that MoSx/GO using the medium degree of oxidation of \GO\ as matrix exhibits best electrocatalytic activity for \HER\ with a small overpotential of ?195
