Abstract：Using tetraethyl titanate as titanium source and 3-aminopropyltrimethoxysilane as reactant， aminated nano-TiO2 was prepared by uniform hydrolysis-thermal decomposition method， then Ag/TiO2 was prepared by doping Ag nanoparticles， and its photocatalytic performance was studied. The results show that Ag-doped nano-TiO2 has better photocatalytic reaction with printing and dyeing waste water than non-doped TiO2， and the photocatalytic degradation rate of calcined Ag/TiO2 is higher. The Ag/TiO2 doped with 3% Ag（mass percent） has the best photocatalytic effect. The after-doping Ag means that Ag is actually coated on the surface of nano-TiO2， which saves more raw materials than Ag/ TiO2 prepared by mixing.
