Abstract

The dark and photocatalytic properties of Ni-doped WS2 supported on SiO2 were investigated. Adding Ni increases the dark catalytic hydrogen evolution activity of Ni-doped WS2 maximizes at intermediate Ni loading levels. With fluorescein as a sensitizer, the addition of Ni lowers the activity of WS2. These results are interpreted in terms of a model in which Ni on the surface of WS2 plays an important role in controlling the surface geometric and electronic properties of the substrate and thereby the efficiency of interfacial energy and charge transfer.
