Abstract :
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.
