Ni-modified β-FeOOH nanorod cocatalysts for oxygen evolution utilising photoexcited holes on a N 2p level in a N-doped TiO2 electrode

Abstract

Traditionally, N-doped TiO2 (N-TiO2) 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-TiO2 photoanode induced by 400–500 nm visible light photons for the OER, enhancing anodic photocurrent of N-TiO2 with 13-fold with 100% faradaic efficiency.
