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.
