摘要(Abstract)：                

通过X射线衍射(XRD),扫描电子显微镜(SEM)和X射线光电子能谱(XPS)的表征,发现g-C_3N_4-TH,g-C_3N_4-CU,g-C_3N_4-CA,g-C_3N_4-HAc具有类似的片层结构.紫外-可见漫反射吸收光谱(UV-Vis DRS)得出制备样品的禁带宽度呈现:g-C_3N_4>g-C_3N_4-TH>g-C_3N_4-CU>g-C_3N_4-HAc>g-C_3N_4-CA.荧光光谱(PL)分析得出g-C_3N_4-CU的光生电子-空穴的分离效率要高于g-C_3N_4.以15 mg/L甲基橙为模拟污染物考察所制备材料的可见光催化性能,结果发现g-C_3N_4-CU的降解性能最好,是g-C_3N_4降解效率的3.2倍.
