Mechanically and photoelectrochemically stable WO 3 |BiVO 4 |NiFeOOH photoanodes synthesised by a scalable chemical vapour deposition method

Scalable and stable WO 3 |BiVO 4 |NiFeOOH photoanodes were fabricated by a novel chemical vapour deposition method. Excellent mechanical and photoelectrochemical stability was achieved over 24 hours in a PEC flow cell.
