摘要
采用溶胶—凝胶法制备了TiO2 光催化材料 ,在太阳光的照射下进行了加有Fe3+的染料溶液的光催化降解。实验结果表明 ,加有Fe3+后 ,TiO2 的自然光催化活性显著高于未加Fe3+的染料溶液 ,其与TiO2 在紫外灯下的催化活性相当。并对其催化机理进行了讨论。
TiO 2 photocatalysis materials were prepared by sol-gel method and some dye solutions with or without Fe 3+ were treated under solar ray.The results show that photocatalytic properties of TiO 2 were improved when Fe 3+ was added to the dye solution,and its photocatalytic mechanism was discussed.
