Nanostructuring has been an effective method to improve the charge separation of semiconductors with poor charge transport properties. FeVO4is a promising photoanode with a band gap of ∼2.1 eV, theoretical photocurrent of 13 mA cm-1, and solar-to-hydrogen efficiency of up to 16%. However, its photoe...
