Self-doped Ti3+–TiO2as a photocatalyst for the reduction of CO2into a hydrocarbon fuel under visible light irradiation
2015
Nanoscale
Preserved Fulltext
Self-doped TiO 2 shows visible light photocatalytic activity, while commercial TiO 2 (P25) is only UV responsive. The incorporation of Ti 3+ into TiO 2 structures narrows the band gap (2.90 eV), leading to significantly increased photocatalytic activity for the reduction of CO 2 into a renewable hydrocarbon fuel (CH 4 ) in the presence of water vapour under visible light irradiation. † Electronic supplementary information (ESI) available: Experimental details, XPS, XRD and SEM images.
