Defect engineering of codoped visible light photosensitized TiO2:WN thin-films for efficient electro-photocatalysis

Anionic doping, such as nitrogen doping is widely used to visible-light photosensitize TiO2. Unfortunately, this promotes the formation of oxygen vacancies (VO), reducing the per-photon efficiency of TiO2:N. Herein we propose a solution based on defect engineered acceptor-donor passivation of the el...
