MoCoFeS hybridized with reduced graphene oxide as a new electrocatalyst for hydrogen evolution reaction

The produce of high-efficiency materials in hydrogen evolution technology is a priority. Recent development in graphene-based material shows that it can be a good candidate for this target. Accordingly, the MoCoFeS/reduced graphene oxide (rGO) catalyst was prepared by the hydrothermal method for hydrogen evolution reaction. The catalysts were characterized and the effect of rGO on the electrochemical properties of the catalyst was examined. Our results are encouraging that, the optimized catalyst (MoCoFeS/rG00.4) at -110 mV overpotential with a Tafel slope of 50.26 mV dec(-1) can be a novel candidate for an active non-precious metal hydrogen evolution reaction catalyst.
