用Fe3+掺杂锐钛矿型TiO2光催化剂降解孔雀石绿

摘要

The Fe3 +-dopedanatase TiO2 ( Fe3 +-TiO2) powder was prepared by hydrothermal method using titanium sulfate as raw material and characterized by SEM. The degradation of malachite green on Fe3 + -TiO2 was studied. Under the conditions of malachite green mass concentration 2 mg/L, Fe3 * -TiO2 dosage 1.616 g/L, Fe3+doping amount 8% (mass fraction) and illumination time 4 h, the degradation rate of malachite green is 84. 00%.%以硫酸钛为原料,用水热法制备了Fe3+掺杂锐钛矿型TiO2(Fe3+ - TiO2)粉末,用扫描电子显微镜测定了试样的形貌.研究了自制的Fe3+ - TiO,光催化剂对孔雀石绿的光催化降解作用.实验结果表明,在孔雀石绿溶液质量浓度为2 mg/L、Fe3+ - TiO2加入量为1.616 g/L、Fe3+-TiO2中Fe3+掺杂量(摩尔分数)为8％、光照时间为4h的条件下,孔雀石绿降解率达84.00％.
