Photocatalytic fixation of nitrogen to ammonia with a Ce/S co-doped TiO2 catalyst: synergistic tuning of heterovalent metal states and oxygen vacancy defects

A novel Ce/S co-doped TiO 2 sulfur-oxide catalyst (labeled TiCeOS) with heterovalent metal states and oxygen-vacancy defects was synthesized for effective photocatalytic nitrogen fixation into ammonia under visible light.
