Electrocatalytic hydrogen evolution is the most cost-effective method for producing hydrogen as a large-scale clean energy source. Thus, catalysts of low-cost hydrogen evolution are developing at great speed. FeS2-reduced graphene oxide (RGO) hybrid catalysts are synthesized with the use of abundant and inexpensive component worldwide. The catalyst has satisfactory electrocatalytic performance and excellent stability in 0.5M H2SO4 solution. The catalyst supported by RGO is the ideal electrocatalyst with satisfactory electrical conductivity with 61mVdec(-1) of the Tafel slope. What is more, the current density changes slightly in 36h and the catalytic performance is relatively stable at 200mV overpotential. Therefore, the catalyst supported by RGO has high potential for industrial production due to its simple composition and satisfactory electrocatalytic effect.
