英文摘要: Reduced TiO2 (TiO2-x) materials have attracted increasing attention due to their large solar absorption and high photo-activity. However, their synthesis procedures usually involve harsh conditions, such as high temperature and/or high pressure. Herein, a facile solid ball-milling method for the synthesis of TiO2-x under ambient conditions was developed. By using finely dispersed Na/NaCl powders as the reducing agent and TiO2 (P25, Degussa) as the precursor, a series of TiO2-x of 20-30 nm with a controllable reduction degree can be successfully synthesized through adjusting the reaction conditions. The surface area of TiO2-x is much larger than that of pristine TiO2, showing its great potential as a catalyst support in chemical reactions. Our experimental results show that uniform Ru particles with particle size less than 1 nm can be well dispersed on the surface of the TiO2-x due to the enhanced surface area and plenty of oxygen vacancies in TiO2-x. As a result, Ru/TiO2-x exhibited superior activity upon catalytic hydrogenation of N-methylpyrrole in comparison with Ru/TiO2.
