Photocatalyst Tio2 Supported on Bentonite for Water Organic Pollutants Purification: A Literature Review

摘要

Photocatalytic degradation of waste pollutants using TiO2 is a promising technology.Recently,the use of bentonite for the removal of organic pollutants was widely studied because of large specific surface areas.Studies have shown that TiO2 supported on bentonite,or TiO2/bentonite composite,exhibits bifunctionality of adsorption and photocatalysis in synergism.This paperpresents a literature review of the preparation and modification techniques of bentonite/TiO2 composite photocatalyst,and their characteristics.The review will also focus on the current researches on the degradation of water organic pollutants by using bentonite/TiO2 composite photocatalyst and its key influencing factors.
