| 摘 要： | 用溶胶-凝胶法制备了La、N共掺杂的TiO2光催化剂,以甲基橙为模拟污染物,考察了其光催化活性。结果表明,La-N共掺杂TiO2光催化剂与单掺N的TiO2以及纯TiO2相比,光催化活性有明显提高,当煅烧温度为600℃,添加La的摩尔分数为0.10%时,光催化活性最佳。

| Abstract: | The La and N co-doping TiO2 composite photocatalyst were prepared by sol-gel method.The photocatalytic activity was investigated by the photocatalytic degradation of methyl orange.It is found that the photocatalyst has higher photocatalytic activity,when the calcined temperature is 600 ℃,the photocatalytic activity of 0.10% La(in mole) added is the best of all the prepared samples. |
