Abstract: In order to improve the electrocatalytic hydrogen evolution performance of anode materials of lithium ion battery,the reduced graphene oxide (RGO) nanosheets loaded with WS2 and SnS2 composite nanomaterials are prepared via a simple hydrothermal method by using graphene as a carrier.The results from electrochemical performance test show that the overpotential of the prepared composite in a 0.5 mol·L-1 H2SO4electrolyte solution is 180 mV and its Tafel slope is 129 mV·dec-1 when the mass ratio of SnS2 to WS2 is 1:2,and the current density is 10 mA·cm-2.The environmentally friendly synthesis method and excellent performance show that SnS2/RGO/WS2 composite nanomaterial has a great potential as an electrocatalyst without precious metals.
