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.
