| 摘 要： | 以TiOSO4和ZnSO.47H2O为原料,NH3.H2O为沉淀剂,采用超声波-微波化学共沉淀法制备具有可见光催化活性的N、Zn共掺杂纳米TiO2纳米粉体,并用XRD、UV-VIS对其进行了表征。在可见光下,考察了N、Zn共掺杂纳米TiO2光催化降解甲基橙的光催化性能。通过正交试验得出降解甲基橙的最佳工艺条件,并在最佳条件下做验证实验得出在太阳光下照射6h,光催化剂重复使用4次后降解率仍可到达74.2%,有超声分散、搅拌的条件下降解甲基橙降解率达到98.2%。

| Abstract: | N、Zn co-doped TiO2nanometer photo-catalysts(NZT),which have photo-catalysis in invisible spectral rang,were prepared with TiOSO4 and ZnSO4.7H2O as raw materials,NH3.H2O as precipitant by co-precipitation method.It was characterized by XRD and UV-VIS.Photo-catalytic activities of N、Zn co-doped TiO2 catalysts under visible light irradiation by photo-degradation of methyl orange.Verification experiment in the optimum conditions showed that the degradation ratio of methyl reached 98.2%,under sunshine for 6h,with ultrasound dispersing and whipping,and it’s still 74.2% four times reused. |
