Traditionally, N-doped TiO 2 (N-TiO 2 ) has been regarded as unsuitable for the oxygen evolution reaction (OER) under visible light. Ni-modified β-FeOOH nanorod cocatalysts enabled to use N 2p holes in the N-TiO 2 photoanode induced by 400-500 nm visible light photons for the OER, enhancing anodic photocurrent of N-TiO 2 with 13-fold with 100% faradaic efficiency.
