摘要

提高光催化剂的光催化活性,以及将光催化剂固定于合适的载体表面,这是多相光催化技术工业处理应用中的关键。单一半导体光催化剂的光催化活性普遍不高,通过改性可以提高光催化活性,甚至在提高活性的同时扩展光谱响应范围,提高光的利用率。而将光催化剂固定在合适的载体表面,可免去光催化剂的分离回收工序,以及消除粉末悬浮体系中存在的易聚集、流失等缺点。

Abstract

It' simpo rtant for the modification and fixation of photocatalyst to be used in water t reatment.The activity of mono-photocataly sts is usually low, but it can be improved by the modification of photocatalyst.Through the modificat ion and fixation of photocatalyst, the spectral response can be enlarged, and the utilization of light can be enhanced.The disadvantages such as the agg regation and the bleeding of the photocatalyst can be overcome.
