摘　　要：以硅藻泥为硅源合成了ZSM-5分子筛;以三聚氰胺为前驱体制备g-C_(3)N_(4),将合成的分子筛(未去除模板剂)与三聚氰胺混合加热,去除模板剂的同时,合成ZSM-5分子筛@g-C_(3)N_(4)。分别用XRD,SEM,TEM,EDS,DTA等对样品进行表征分析,以亚甲基蓝模拟目标污染物,分别考察ZSM-5分子筛@g-C_(3)N_(4)投加量,亚甲基蓝溶液pH,初始浓度和光催化时间对光催化性能的影响。实验结果表明,在样品投加量为8 g·L^(-1)、光照时间为3 h,亚甲基蓝初始浓度为5 mg·L^(-1)、pH=11时对亚甲基蓝去除率可达到92.43%。Diatom ooze was used as silicon source to synthesize ZSM-5 zeolite and melamine was used as the precursor to obtain g-C_(3)N_(4).Then,the as-synthesized molecular sieves(without removing the template agent)and the melamine were mixed and heated.After that,ZSM-5 zeolite@g-C_(3)N_(4) was synthesized with the removal of the template agent.The samples were characterized by using XRD,SEM,TEM,EDS and DTA.With methylene blue as the target pollutant,photocatalytic performance of the ZSM-5 zeolite@g-C_(3)N_(4) was studied,in terms of dose quantity,pH value,initial concentration and illumination time.W hen the ZSM-5 zeolite@g-C_(3)N_(4) dose quantity was 8 g·L^(-1),illumination time was 3 h,initial concentration was 5 mg·L^(-1) and the pH value was 11,the degradation rate of methylene blue was as high as 92.43%.
