摘要
以四异丙醇钛和三乙胺为原料,通过水解法合成TiO2。三聚氰胺于580℃煅烧得到g-C3N4,g-C3N4与TiO2按一定比例混合,在超声波条件下加入适量的甲醇得到复合材料g-C3N4/TiO2。以甲基橙为光催化反应模型考察了复合材料的紫外光催化活性。结果表明,g-C3N4/TiO2具有良好的光催化活性,用量3%时,甲基橙脱色率达96.6%。
With Ti（ OC3 H7 ）4 and N（ C2 H5 ）3 as raw materials,TiO2 was synthesized by the method of hy-drolysising,g-C3 N4 could be obtained by tripolycyanamide calcined at 580 ℃. Composite materials of g-C3 N4/TiO2 could be prepared by mixing g-C3 N4 and TiO2 according to certain proportion which the mod-erate methanol was added under the condition of ultrasonic. The photocatalytic activities of g-C3 N4/TiO2 have been evaluated by photocatalytic degradation of methyl orange under UV light. The results show that the composite materials of g-C3 N4/TiO2 have good photocatalytic activities,and photocatalytic degradation rate of methyl orange can reach 96 . 6% when the quality percentage is 3%.
