Low-temperature fabrication of brown TiO2 with enhanced photocatalytic activities under visible lightElectronic supplementary information (ESI) available. See DOI: 10.1039/c5cc09176d

Here we report a facile one-step low-temperature solution-based method to treat native TiO 2 with NaH. The NaH treatment effectively induces the Ti( iii ) species and oxygen vacancies into the TiO 2 host lattice, and enables the absorption edge of TiO 2 to be conveniently adjusted from the UV region...

Summary:Here we report a facile one-step low-temperature solution-based method to treat native TiO 2 with NaH. The NaH treatment effectively induces the Ti( iii ) species and oxygen vacancies into the TiO 2 host lattice, and enables the absorption edge of TiO 2 to be conveniently adjusted from the UV region to the red end of the visible spectrum. Brown-colored TiO 2 with the absorption edge in red light was fabricated using a facile one-step treatment in NaH solutions.
