摘要： 以TiCl4为前驱体,采用水热法制备了掺杂铁离子的TiO2纳米粒子,利用XRD对不同条件下制备的产物进行了表征,探讨了反应温度、胶体溶液pH值和反应时间对水热反应的影响.考察了所制备的Fe3+-TiO2纳米粒子光催化降解罗丹明B的催化性能,实验发现,制备的掺杂0.1%Fe3+-TiO2纳米粒子与纯TiO2相比,具有更好的催化活性.

Abstract: Nanosize Fe3+-doped TiO2 particles were prepared by the hydrothermal method with TiCl4 as the precursor. The products obtained under different conditions were characterized by means of XRD. The influences of various hydrothermal conditions including reaction time, temperature, and pH were investigated. The photocatalytic activity of the catalysts was tested with Rhodamine B as the objective decomposition substance. The results show that the 0.1%Fe3+-doped TiO2 has a higher photocatalytic activity than TiO2.
