The effect of reduced graphene oxide on MoS2 for the hydrogen evolution reaction in acidic solution

Abstract The pure MoS 2 and MoS 2 @reduced graphene oxide were synthesized on commercially available Ti plate by one-step hydrothermal method. The hole microspheres were successfully synthesized. The resulting MoS 2 @reduced graphene oxide electrode on Ti plate exhibited higher catalytic activity than pure MoS 2 electrode on Ti plate for hydrogen evolution reaction. In addition, the excellent cycling stability was also obtained in MoS 2 @reduced graphene oxide electrode on Ti plate. Such enhanced catalytic activity and excellent cycling stability occurred due to the abundance of catalytic edge sites, high specific surface area and the unique synergic effects between the MoS 2 and reduced graphene oxide.
