摘要
以TiO2 为代表的半导体多相光催化反应已有许多报道 ,但其在降解过程中的反应机理还在不断研究中。该文将具有不同Zeta电位的TiO2 ,通过光照、通电以及紫外光照射等不同的催化反应条件 ,得出TiO2 - 3.0光催化降解效果最好 ,结果表明悬浮颗粒的Zeta电位对半导体光催化反应有较大影响。
There have been many reports on heterogeneous photocatalysis of semiconduction in behalf of TiO 2 ,but the mechanism in the process of degradation is still being studied. The paper has put TiO 2 which has different Zeta potential under the different catalytical condition of the general lighting, UV radiate and through electricity and draw a conclusion that TiO 2 -3.0 does best in photocatalysis degradation. The result shows that Zeta potential has a great effect on photocatalysis reaction.
