Preparation of Nano-TiO2 and Performance Study on Photocatalytic Degradation of Methylene Blue

摘要

Experiment of photocatalytic degradation was conducted through using tetra-n-butyl titanate and ethyl alcohol as raw material,adopting sol-gol method to prepare photocatalyst of nano-TiO2 and using methylene blue solution as analogue dye wastewater.The influences of hydrolyzing temperature,PH value,different water addition,and different speed of adding drops were investigated,as well as the reuse rate of photocatalyst.
