摘　　要：以氰胺废渣为模板用煅烧法制备g-C3N4,采用比表面积仪、扫描电镜、红外光谱仪、X-ray衍射仪等分析测试手段对形貌和结构表征进行分析,并通过催化H2O2降解亚甲基蓝溶液对其催化性能进行探究,实验结果表明:氰胺废渣与双氰胺的质量比为40%催化性能最佳,g-C3N4催化H2O2降解亚甲基蓝溶液过程中HO^-和·O^-2自由基是g-C3N4和H2O2体系的主要氧化自由基,其中O^-2自由基起主要作用。g-C3N4 was prepared by adding different amount of dicyandiamide waste residue as template, The morphology and structure of porous g-C3N4 were characterized by specific surface area analyzer, scanning electron microscope, infrared spectrometer and X-ray diffractometer.and the degradation of methylene blue solution by H2O2 catalyzed by g-C3N4 was studied. It was determined that the mass ratio of dicyandiamide residue to dicyandiamide was 40%. I HO^- and ·O^-2 free radicals are the main oxidative free radicals in g-C3N4 and H2O2 systems during the degradation of methylene blue solution by H2O2 catalyzed by g-C3N4 . Among them, O^-2 free radical plays a major role.
