Abstract
Single‐source precursors are used to produce nanostructured BiVO4 photoanodes for water oxidation in a straightforward and scalable drop‐casting synthetic process. Polyoxometallate precursors, which contain both Bi and V, are produced in a one‐step reaction from commercially available starting materials. Simple annealing of the molecular precursor produces nanocrystalline BiVO4 films. The precursor can be designed to incorporate a third metal (Co, Ni, Cu, or Zn), enabling the direct formation of doped BiVO4 films. In particular, the Co‐ and Zn‐doped photoanodes show promise for photoelectrochemical water oxidation, with photocurrent densities >1 mA cm−2 at 1.23 V vs reversible hydrogen electrode (RHE). Using this simple synthetic process, a 300 cm2 Co‐BiVO4 photoanode is produced, which generates a photocurrent of up to 67 mA at 1.23 V vs RHE and demonstrates the scalability of this approach.
