摘要
以钛酸正丁酯和自制颗粒为主要原料,采用溶胶-浸渍法制备出负载型纳米TiO2催化剂,对甲基橙模拟废水进行了光催化降解研究。分析并比较了负载与非负载TiO2降解效果的差异及影响因素。结果表明,120 min后负载型TiO2与非负载TiO2对甲基橙的光催化降解率分别达到99.7%和78.1%,第二次使用的降解率则分别达到90.4%和57.3%。
Titania/ball photocatalyst was prepared by sol-gel impregnation method using tetrabutyl titanate and self-made ball as the raw material, and be used as the catalyst for photocatalytic degradation of model compound methyl orange. The catalytic results were compared between supported and non-supported-titania and the influencing factor. The results showed that the degradation rate of the former was 99.7% and the latter was 78.1% after 120 rain,the second use was 90.4% and 57.3% ,respectively.
