title: Selective synthesis of pure cobalt disulfide on reduced graphene oxide sheets and its high electrocatalytic activity for hydrogen evolution reaction.
abstract: We synthesized single-phase CoS2on a large scale by adding graphene oxide of sufficient quantity via the hydrothermal method using cobalt acetate and thioacetamide as precursors; this produced the hybrid of CoS2with reduced graphene oxide which exhibited high electrocatalytic activity in the hydrogen evolution reaction.
