摘要
以太阳光为光源,TiO2-ZnO复合材料为光催化剂,在太阳光照射下,以有机染料模拟工业废水为处理对象,研究了自制纳米复合材料TiO2-ZnO的光催化活性,结果表明:在日光照射60min后,有机染料的降解率、CODCr去除率均>90%,复合材料TiO2-ZnO光催化活性高于纯TiO2的光催化活性,光催化反应符合一级动力学方程。
It is found that using sunlight as the light source,the photocatalytic activities of TiO2-ZnO have been investigated of organic dye and the elimination rate of CODCr can be more than 90% after 60 min. This shows that the composite material is more effective than pure TiO2 and the photocatalytic degradation reaction accords with the first grade dynamic equation.
