采用偏钛酸为钛前驱体，三聚氰胺为氮源，制备g-C3 N4/TiO2复合纳米光催化材料，研究不同原料配比、焙烧温度及不同焙烧时间制备的 g-C3 N4/TiO2光催化材料对亚甲基蓝以可见光激发降解亚甲基蓝溶液，考察其光催化活性，采用紫外-可见吸收(UV-Vis)光谱、三维荧光(FS)光谱进行机理研究。
Graphitic carbon nitride (g-C3 N4 )hybridized TiO2 nanometer materials was prepared by annealing metatitanic acid and melamine.Different ratio,different roasting temperature & different roasting time was adopted while g-C3 N4 degraded methylene blue.Mechanism of photodegradation was discussed using UV-Vis spectrometer & fluorescence spectrometer.
