Low-temperature fabrication of brown TiO2 with enhanced photocatalytic activities under visible light. Issue 14 (19th January 2016) - Wang, Mingzheng
Abstract : Brown-colored TiO2 with the absorption edge in red light was fabricated using a facile one-step treatment in NaH solutions. Abstract : Here we report a facile one-step low-temperature solution-based method to treat native TiO2 with NaH. The NaH treatment effectively induces the Ti(iii ) species and oxygen vacancies into the TiO2 host lattice, and enables the absorption edge of TiO2 to be conveniently adjusted from the UV region to the red end of the visible spectrum.
