| Abstract: | In this paper,the present situation and progress on the area of TiO_2-based solid superacid photocatalysis were reviewed briefly,including the performance of TiO_2-based solid superacid photocatalysis,preparation of TiO_2-based solid superacid photocatalysts.The results indicated that the structure and photocatalytic properties of TiO_2 were greatly improved by sulfation.It was found that both B acid sites and L acid sites exist on the SO~(2-)/TiO_2 catalyst,forming cooperative centers with superacidic characteristics.When compared to unmodified TiO_2,the SO~(2-)_4/TiO_2 catalyst exhibited higher photocatalytic properties,stability,and moisture resistance.The application of TiO_2-based solid superacid photocatalysis is also previewed. |
| Keywords: | solid superacid TiO_2 SO~(2-)_4/TiO_2 |
