摘要
In this work, both hydrogenated and F-doping strategies are adopted to synergistically enhance the photocatalytic properties of TiO2 under solar light irradiations. The hydrogenated F-doping TiO2 is successfully synthesized by a facial two-step method and characterized with physicochemical and spectroscopy methods. It is found that the F-doping strategy can effectively enhance the UV-light absorption property of TiO2, and the hydrogen treatments can further increase the light absorption performance of TiO2 in the visible light region. As a result, the hydrogenated F-doping TiO2 exhibits better photocatalytic properties than pure, hydrogenated or F-doped TiO2, in either hydrogen production or organic pollutant degradation. The present work provides a suitable and synergistic strategy to enhance the photocatalytic activity of TiO2.
