Abstract

Composite materials: Tungsten disulfide and WS₂/reduced graphene oxide (WS₂/rGO) nanosheets were fabricated by hydrothermal synthesis using tungsten chloride, thioacetamide, and graphene oxide (GO) as starting materials. The WS₂ nanosheets are efficiently templated on the rGO layer. The WS₂/rGO hybrid nanosheets show much better electrocatalytic activity for the hydrogen evolution reaction (see picture) than WS₂ nanosheets alone.
