摘要
采用溶胶-凝胶法制备了镧掺杂二氧化钛光催化剂,并利用莠去津模拟废水考察了其催化性能。在紫外光照射4h条件下探讨了焙烧温度、焙烧时间、镧掺杂量(摩尔百分比)对镧掺杂二氧化钛光催化剂催化性能的影响,利用正交分析得到了催化剂制备的最佳实验条件:焙烧温度为500℃,焙烧时间为2.5 h,镧掺杂量为0.5%,该条件下制备的镧掺杂二氧化钛光催化剂处理莠去津废水的催化降解效率可达80%以上。
La-doped TiO2 photocatalyst was prepared by sol-gel method and its catalytic performance was investigated by using atrazine simulated wastewater.The effects of calcination temperature,calcination time and Ladoping content(mole percentage)on the catalytic performance of La-doped TiO2 photocatalyst were studied under the condition of ultraviolet irradiation for 4 h.The optimum experimental conditions for the preparation of the catalyst were obtained by orthogonal analysis:calcination temperature was 500℃,calcination time was 2.5 h,and La-doping content was 0.5%.The La-doped TiO2 photocatalyst prepared under this condition was studied.The catalytic degradation efficiency of atrazine wastewater can reach more than 80%.
