摘　　要：g-C3N4/TiO2 composite were prepared by hydrolysis of Ti（OC4Hn9） 4 and the precursors of g-C3N4 at room temperature and annealing in nitrogen atmosphere.X-ray diffraction results revealed that all the products were anatase structure.The chemical nature of O,N of the g-C 3N4/TiO2 were identified by X-ray photoelectron spectroscopy,presenting N-Ti-O and N-Ti-N doping status of the composite.The g-C3N4 /TiO2 composite showed better photocatalytic activity for the UV and visible-light degradation of Rhodamine B.g-C3N4/TiO2 composite were prepared by hydrolysis of Ti（OC4Hn9） 4 and the precursors of g-C3N4 at room temperature and annealing in nitrogen atmosphere.X-ray diffraction results revealed that all the products were anatase structure.The chemical nature of O,N of the g-C 3N4/TiO2 were identified by X-ray photoelectron spectroscopy,presenting N-Ti-O and N-Ti-N doping status of the composite.The g-C3N4 /TiO2 composite showed better photocatalytic activity for the UV and visible-light degradation of Rhodamine B.
