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

The pure MoS₂ and MoS₂@reduced graphene oxide were synthesized on commercially available Ti plate by one-step hydrothermal method. The hole microspheres were successfully synthesized. The resulting MoS₂@reduced graphene oxide electrode on Ti plate exhibited higher catalytic activity than pure MoS₂ electrode on Ti plate for hydrogen evolution reaction. In addition, the excellent cycling stability was also obtained in MoS₂@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 MoS₂ and reduced graphene oxide.
