| 摘 要： | 溶胶-凝胶和浸渍相结合的方法制备Mn2+-WO3-TiO2光催化剂,进行甲基橙的光催化降解实验,考察WO3和Mn2+掺入量、焙烧温度及时间对光催化性能的影响。结果表明,500℃焙烧2h,掺杂量n(Mn2+)∶n(WO3)∶n(TiO2)=0.8∶1∶100时,光催化活性最高,光催化降解甲基橙溶液,120min后,降解率达84%,比单纯TiO2的光催化活性提高83%。

| Abstract: | Experiment on photocatalytic degradation of methyl orange was conducted with Mn2+-WO3-TiO2 photocatalyst prepared by sol-gel and impregnation method to investigate the effect of WO3 and Mn2+-doped dosage,calcinations temperature and calcinations time on photocatalytic activity.Results showed that the photocatalysis performance is the best when ratio of Mn2+,WO3 and TiO2 was 0.8:1:100 and calcined at 500℃ for 2h.After 120min,the degradation efficiency of methyl orange is 84%,which is 83% higher than the activity of pure TiO2. |
