摘　　要：以尿素为初始原料,用高温热解方法制备纳米片层结构的石墨相氮化碳(g-C_3N_4),并通过X射线衍射(XRD)、X光电子能谱(XPS)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)及Fourier变换红外光谱(FTIR)对样品的结构和形貌进行表征,用罗丹明对样品的光催化性能与循环催化性能进行测试.结果表明,g-C_3N_4纳米片具有较高的光催化活性及循环催化性能.Using urea as the starting material,we prepared the lamellar structure of graphite carbon nitride（g-C_3N_4）by high-temperature pyrolysis method.The structures and morphologies of the samples were characterized by X-ray diffraction（XRD）,X photoelectron spectroscopy（XPS）,scanning electron microscopy（SEM）,transmission electron microscopy（TEM）and Fourier transform infrared spectroscopy（FTIR）.Rhodamine was used to test the photocatalytic and cyclic catalytic performances of the sample.The results show that the g-C_3N_4 nanosheets have high photocatalytic activity and cyclic catalytic performance.
