With the improvement of people´s living standard, many people focus on environmental pollution. Indoor and outdoor air pollution, water pollution and etc. influence people´s physical health seriously. Using photocatalytic properties of semiconductor materials to remove pollutants has attracted world wide attention. In this paper modified microporous zeolite balls have been prepared by experiment at first, and then nano-TiO₂ photocatalyst doping V⁵⁺, Ag⁺ has been loaded on zeolite balls by sol-gel. Microporous structure of modified microporous zeolite ball is obvious. Doped TiO₂ photocatalyst was characterized by SEM; Results show that the photocatalyst can play a significant degradation effect on methyl orange solution. Photocatalytic degradation rate is 68% at 4h.
