Bismuth vanadate (BiVO4) is a nontoxic and medium band gap (2.4 eV) n-type semiconductor that has attracted worldwide attention as a visible-light active photocatalyst. Particularly, scheelite monoclinic BiVO4 is one of the most active polymorphs in photocatalytic oxygen evolution. However, the oxidation capability of bare BiVO4 is hindered by weak charge carrier mobilities, short charge carrier diffusion lengths, and a high charge recombination rate at the surface. To circumvent these inconveniences, heterostructuring by contacting BiVO4 with other materials such as noble metals and metal oxides has been proposed.
