摘　　要：以钛酸四丁酯、尿素、无水乙醇为原料,采用水热合成方法制备了掺氮和不掺氮的二氧化钛前驱体。以250W高压汞灯为光源,达旦黄水溶液为活性评价体系,设计正交表研究了N-TiO2光催化实验的最佳条件。研究了N-TiO2对不同拟污染物的降解能力,分析了可见光条件下N-TiO2和TiO2光催化活性。N-TiO2 and TiO2 precursor was prepared from Ti（OC4H9）4,urea and C2H5OH by hydrothermal synthesis.The optimum condition for N-TiO2 photocatalysis of dye titan yellow solution as the activity evaluation system was investigated through orthogonal test toward 250W high pressure mercury as lamp.The degradation ability of different suppositional pollutant was considered and photocatalytic performance between N-TiO2 and TiO2 was analyzed under visible light.
