银修饰催化剂对TiO2光催化活性的影响

Effect of Silver-decorated Catalyst on Photocatalytic Activity of TiO2

该研究通过采用一步浸渍热解硝酸盐法来制备Ag-TiO2纳米颗粒,以甲基橙为检测物测试Ag-TiO2纳米颗粒的光催化性能.结果表明,银的负载量及催化剂制备时的条件对光催化效果是有影响的,TiO2负载1%的银,选取烧结温度为300℃时的光催化效果是最好的.

The Ag-TiO2 nanoparticles were prepared by one-step impregnation pyrolysis nitrate method, and the photocatalytic properties of Ag-TiO2 nanoparticles were tested with methyl orange as a test substance. The results show that the loading of silver and the conditions of catalyst preparation have an effect on the photocatalytic effect. TiO2 is loaded with 1% silver, and the photocatalytic effect was optimal when the sintering temperature was 300℃.
