Fe 2+ and Ti 3+ co-doped anatase TiO 2 nanocrystallites with ca. 50% exposed {001} facets have been successfully synthesized by a facile hydrothermal method. The transition metal dopant induces the stability of Ti 3+ ions in the structure. As-prepared anatase TiO 2 exhibits a broad absorbance in the visible light region, which shows blue colour. Furthermore, these Ti 3+ ions can in situ reduce the noble metal cations to neutral atoms, which form homogeneously nanoclusters on the TiO 2 surface. The noble metal anchored samples show enhanced photocatalysis compared to the original Fe,Co-doped TiO 2 sample under ultraviolet light. Among the noble metal anchored samples, Pd@Fe3–TiO 2 can completely oxidize CO at the mild temperature above 250 °C. [ABSTRACT FROM AUTHOR]
