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 a dopant to modify the nano titanium dioxide, and through the degradation of methylene blue, acid fuchsine, rhodamine B, malachite green four kinds of organic dyes to test the photocatalytic performance of the catalyst and Add cocatalyst hydrogen peroxide, photocatalyst in the light of the three-color energy-saving lamps, and sunlight, the ambient temperature and pressure without the introduction of oxygen degradation of organic dyes, and achieved good results. The photocatalytic activity of Eu3 + rare earth doped nano-TiO2 was the best at the concentration of 0.05% Eu3 + / TiO2. The best photocatalytic activity of La3 + / TiO2 was 0.5% La3 + / TiO2. The Sm3 + rare earth doped nano-TiO2 concentration was 0.1% Sm3 + / TiO2 The photocatalytic performance of Ce3 + rare earth doped nano-TiO2 is best.
