摘要
本文以染料废水中阳离子型染料罗丹明B(RhB)和阴离子型染料甲基橙(MO)为研究对象,对自制的新型光催化剂(石墨烯基-石墨相氮化碳复合光催化剂)的可见光响应光催化降解特性进行了研究。结果表明,与具有可见光催化性能的石墨相氮化碳比较,石墨烯基-石墨相氮化碳复合光催化剂的可见光催化活性得到显著改善。石墨烯基复合光催化剂的催化活性具有良好的稳定性,可以重复使用。
In this study,cationic dye rhodamine B(RhB)and anionic dye methyl orange(MO)were used as the target pollutants in dyeing wastewater to indicate the visible light catalytic performance of the homemade graphene-based composite photocatalyst.The results showed that the visible light photocatalytic activity of graphene-graphite phase carbon nitride composite photocatalyst was significantly improved compared with g-C3N4 with visible light catalytic properties.The photocatalytic activity of the graphene-based composite photocatalyst is stable,and can be reused.
