| 摘 要： | TiO2是当前最有应用潜力的光催化材料,但其量子效率低、降解效果不理想、难以充分利用太阳能。选用合适的掺杂组分、制备方法和载体,制备出具有宽光谱响应范围、光量子效率高、易于回收利用的TiO2/载体光催化材料,对实现TiO2的工业化应用具有重大意义。根据半导体能带理论和异质结构的工作原理,研究各种表面改性技术和研制新的光催化剂,将是今后研究的主要方向。 |

| Abstract: | TiO2 is the materials which has the greatest potential for photocatalysis application at present, but its quantum efficiency is low, its degradation result is not very good and it can hardly make full use of solar energy. In order to prepare the TiO2/carrier photocatalysis materials which has the broad light spectrum response scope, high photo quantum efficiency and to be easily recovered and utilized, we should select suitable doped component, preparation method and carrier. This has the significant purport to realize its industrialization application. It is the main direction to apply a large kinds of surface technique and develop new photocatalyst according to the work principle of the semiconductor energy band theory and heterogeneous medium structure. |
