TiO2/g-C3N4 composite photocatalytic material was prepared by uniformly mixing nano TiO2 with urea and then sealed pyrolysis.The material was characterized by X-ray diffractometry,fourier transform infrared spectroscopy and scanning electron microscope.The visible light degradation property of TiO2/g-C3N4,degradation selectivity and cycle degradation life were investigated.The results shown that the composite material was succeeded to couple TiO2 and g-C3N4.The fabricated TiO2/g-C3N4 had better degradation property than pure g-C3N4,with the 2.22 times reaction rate constant than pure g-C3N4.Rhodamine (RhB) was degraded best by TiO2/g-C3N4.After 5 cycles,the degradation efficiency reduced by 14.3%.The prepared TiO2/g-C3N4 composite photocatalytic material had a broad application prospect in industrial wastewater treatment.
