Abstract: In this article modified porous zeolite pellet has been prepared by experiments at first, then nano-TiO₂ photocatalyst doped with V⁵⁺ and Ag⁺ ions has been loaded on zeolite pellet by sol-gel process . Modified zeolite pellet has clear porous frame; photocatalytic experiments show that the degrading effect of V⁵⁺ and Ag⁺- doped TiO₂ photocatalyst is obvious and the degrading rate is 70% for 4h.

Key words: zeolite pellet, nano- TiO₂, doping, photocatalytic activity
