Abstract

TiO2 coating on cenospheres was prepared by sol-gel method. The better preparation conditions of TiO2 photocatalysts coating on cenospheres to get a high catalytic activity were investigated. Their phase, microstructure were characterized by using X-ray diffractometry and scanning electron microscopy. Photocatalytic properties were invistigaed by UV-visible photometer. The results show that TiO2 coating on cenospheres with high catalytic activity is obtained with cenospheres pretreated by concentrated sulfuric acid and samples calcined at 600 ºC for 3.5 h. Methylene blue was used as target contaminants and the maximum degradation rate reach 60.83 %. It may be the adsorption of methylene blue by cenospheres and the high specific surface area of TiO2 lead to the high degradation rate.
