Preparation,characterzation and photocatalytic activities of nano-sized TiO2-ZrO2 coupled photocatalysts

摘要

The compoistes TiO2-ZrO2 were prepared by sol-gel method and they were characterized by XRD, nitrogen absorption desorption and TPD techniques. The results indicated these TiO2-ZrO2 were active to decompose Methylene Blue and Rhodamine B aqueous dyes, and their photocatalytic activities were higher than TiO2 and ZrO2.
