摘要
通过溶胶-凝胶法制备了负载型杂多酸/TiO2催化剂,采用该催化剂在可见光条件下对模拟染料废水甲基橙溶液进行光催化脱色降解,并讨论了影响催化降解效率的重要因素.结果表明:光降解的效率与该催化剂和氧化剂的投加量紧密相关,而且该催化剂易回收并有良好的重复性.
A new photocatalytic material which heteropoly acid （HPA） incorporated TiO2 colloids via sol-gel process is synthesized. Aqueous Methyl Orange sollution is degraded in visible light conditions by using HPA/TiO2 as photocatalyst and the factors effecting the efficiency of the photocatalytic degradation are discussed. It is found that the efficiency of the photodegradation is closely related to the amount of catalyst and oxidant. In addition, the catalyst can be easily recovered and can be repeatedly used without loss of efficiency.
