摘要：

以三聚氰胺、三聚氯氰为原料,550℃热聚合法制备了g-C3N4（FCN）。13CNMR、XRD证明该g-C3N4的结构单元是3-s-三嗪环,电镜照片显示FCN形貌为木耳状,边缘较厚。原料三聚氯氰、三聚氰胺分别是4 g和2 g时,N2吸附-脱附测定FCN1的比表面积为156.25 m2/g,孔径60 nm。UV-Vis漫反射测试FCN1的吸收边缘为482 nm,对应禁带宽度2.57 eV,PL光谱显示FCN1光致发光强度最弱。可见光照射下,30 mg FCN1加入30 mL（30 mg/L）的罗丹明B（RhB）溶液中,50 min后RhB的光降解率是99.62%,光催化剂循环实验表明该木耳状g-C3N4具有良好的稳定性。
