P-N co-doping induced structural recovery of TiO2 for overall water splitting under visible light irradiation

We proposed that a phosphorus-nitrogen co-doping could effectively recover the long-range ordered structure of TiO2 crystals and this co-doping effect enables the doped TiO2 to catalyze overall splitting of water under visible light irradiation, in the absence of any sacrificial agents, however that cannot occur for nitrogen doped TiO2 with long-range defect structure.122
