Nature of the Localized V 3 d Electrons in Mo- and W-Doped BiVO4 Revealed by Soft X-ray Photoemission and Absorption Spectroscopy

Abstract We have investigated the effects of Mo and W doping on BiVO4 by means of X-ray photoemission spectroscopy (XPS) and X-ray absorption spectroscopy (XAS). The V 2p XPS spectra indicate that the substitution of W6+ and Mo6+ for V5+ induces the formation of V4+ species. In a...
