摘要
以三聚氰胺为前驱体,通过热聚合法制得片状石墨相氮化碳g-C3N4,采用SEM,TEM,XRD和UV-Vis DRS分析了催化剂的组成、形貌和光吸收性能。以甲基橙为模拟污染物,研究了g-C3N4催化剂的可见光驱动催化活性。结果表明,所得g-C3N4为片状结构,多甲基橙具有较好的可见光催化降解活性。
Using flake- like g- C3N4 as a thermal- polymeration process,XRD,SEM,TEM and UV- Vis- DRS spectrums were employed to investigate the phase composition,morphology and photo- absorption property. The visible- light- driven photocatalytic activities of the g- C3N4 were evaluated by the photodegradation of methylene orange dye（ MO）.The results showed that flake- like g- C3N4 exhibited the excellent best photocatalytic activity for decolorization of MO.
