掺杂对ＰｂＴｉＯ_３光催化活性的影响傅希贤，单志兴，肖坤林，曾淑兰（天津大学化学系天津３０００７２）关键词ＰｂＴｉＯ_３，掺杂，光催化活性，光降解利用半导体材料光催化降解水中污染物是近年发展起来的重要课题之一［１］，一般多采用半导体氧化物为光催化剂，文...
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.
