| 摘 要： | 对自制Ag@TiO2光催化剂日光下光催化降解甲基橙模拟污染物的可行性进行了研究,探讨了反应时间、pH值、H2O2用量、催化剂浓度和催化剂重复使用对甲基橙光催化降解效果的影响.结果表明,在H2O2协同作用下,Ag@TiO2光催化剂可以快速降解溶液中的甲基橙,晴好天气下20 min溶液可褪至无色. |

| Abstract: | A feasible research on photocatalytic degradation of methyl orange model pollutant under solar irradiation by self-made nano-complexed photocatalyst Ag@TiO2 was carried out. The effects of irradiation time, pH value, H2O2 amount, photocatalyst concentration and photocatalyst-reused on photocatalytic degradation of methyl orange were investigated. The results showed that nano-complexed photocatalyst Ag@ TiO2 enabled methyl orange in solution to photocatalytic degrade assisted by hydrogen peroxide. The solution could become colourless under above conditions with solar irradiation for 20 min. The photocatalyst could be reused well. |
| Keywords: | solar light Ag@TiO2 photocatalyst performance H2O2 |
