摘　　要：通过高温分解三聚氰胺制备富氮的g-C_3N_4微米级带状化合物,并对其纳米带的形貌和结构通过X射线衍射(XRD)、扫描电子显微镜(SEM)、化学元素分析(CEA)和X射线光电子能谱(XPS)进行表征.结果表明:制备的带状结构规则均一,带宽约为3～6μm,带长为数百微米或几毫米;样品的石墨相为C_3N_4结构.Nitrogen-rich g-C_3N_4 nanobelts were synthesized via the pyrolysis of melamine（C_3N_6H_6）. The as-synthesized microbelts are structurally uniform,and each belt is uniform in width and thickness along its length direction.The typical width is in a range of 3μm to 6μm.The typical length of the belts is in a range of several hundreds of micrometers,some of which even have a length of millimeters.The structure and morphology were researched by XRD,SEM,CEA and XPS measurement.The result indicates the sample is graphite-C_3N_4.
