摘要
将稀土Ce3+、Sm3+、La3+、Eu3+作为掺杂剂对纳米二氧化钛进行改性,并通过降解亚甲基蓝、酸性品红、罗丹明B、孔雀石绿四种有机染料来测试催化剂的光催化性能研究,并加入助催化剂双氧水,使光催化剂在三基色节能灯的光照下,及日光照射,就能常温常压不需通入氧气的情况下降解有机染料,取得很好的效果。Eu3+稀土掺杂纳米二氧化钛在浓度0.05%Eu3+/TiO2光催化性能最好;La3+稀土掺杂纳米二氧化钛浓度0.5%La3+/TiO2光催化性能最好;Sm3+稀土掺杂纳米二氧化钛浓度0.1%Sm3+/TiO2光催化性能最好;Ce3+稀土掺杂纳米二氧化钛浓度0.5%Ce3+/TiO2光催化性能最好。
The rare earth Ce3 ＋ , Sm3＋ , La3＋ , Eu3＋ as the doping agent on the nanocrystalline TiO2 was modi- dyes to test the photocatalytic performance of the catalyst, cocatalyst and adding hydrogen peroxide, the photocata- lyst sunlight in the three energy saving lamps light, and sunlight, can be at room temperature and atmospheric pres- sure without introducing oxygen degradation of organic dye circumstances, achieved very good results. Eu3＋ rare earth doped nano titanium dioxide is best at a concentration of 0.05% Eu3＋/TiO2 photocatalytic performance of La3＋ doped nano titanium dioxide; photocatalytic performance of the best concentration of 0.5% La3＋/TiO2 ; Sm3＋ doped nano titanium dioxide concentration 0.1% Sm3＋/TiO2 photocatalytic performance is the best; Ce3 ＋~ doped TiO2 photocatalytic performance of the best concentration of 0.5% Ce3＋/TiO2.
