摘要: 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一,一般多采用半导体氧化物为光催化剂.文献报道了钙钦矿型PbTiO3的合成及其对水溶性染科溶液的光降解脱色及影响因素.本文研究掺杂对PbTi03光催化活性的影响及其固载化.

关键词: PbTiO3, 掺杂, 光催化活性, 光降解

Abstract: 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.

Key words: PbTiO3, doping, photocatalytic activity, photodegradation
