Doped BiVO 4 is a promising photoelectrochemical water splitting anode, whose activity is hampered by poor charge transport. Here we use a set of X-ray spectroscopic methods to probe the origin and nature of localized electron states in W:BiVO 4 . Furthermore, using the polarized nature of the X-ray...
