Photocatalytic degradation glyphosate with cerium and nitrogen co-doped TiO2 under visible irradiation

摘要：

　　Cerium and nitrogen co-doped TiO2 nanocrystals were synthesized by a simple sol-gel process,using tetrabutyl titanate as the raw materials with (NH4)2Ce(SO4)3 and urea as ion donors.The co-doped TiO2 nanoparticles were characterized by X-ray diffraction and transmission electro microscopy.The photodegradation of glyphosate has been investigated in aqueous suspensions of doped TiO2 under visible irradiation.The results exhibit a higher thermal stability of anatase than pure TiO2.The uniform test results show the optimal conditions:nce/nTi nN/nTi and calcining temperature was 0.08,0.01 and 800℃.The highest degradation rate for co-doped TiO2 show five times photocatalytic activity of Degussa P25.
