Fu Xixian;Shan Zhixing;Xiao Kunling;Zeng Shulan(Department of Chemistry,Tianjin University,Tianjin 300072)  
Lanthanum,niobium and magnesium doped lead titanates have been prepared by the mixed oxide method.The crystal type of PbTiO3 does not change after doping with these atoms,but its photocatalytic activity is enhanced.Experiments show that organic dyes are photodegraded into small inorganic molecule in La-PbTiO3,syetem under the illumination of a high pressure mercury lamp.
