摘要
光催化技术在污水处理方面具有较好的潜力,然而粉末催化剂在使用中容易造成二次污染问题.文章将石墨相氮化碳(g-C3N4)与聚氯乙烯(PVC)树脂复合,制备了负载型PVC/g-C3N4光催化复合材料,并对其催化性能以及稳定性进行研究.结果表明:g-C3N4负载到PVC,有效降低了g-C3N4团聚,表现较好的催化性能.PVC/g-C3N4-3在光照60 min后,甲基橙和罗丹明B的浓度最低,并且在10次循环后均表现出较好的稳定性.不同类型污水的光催化实验表明,PVC/g-C3N4-3复合材料具有较好的光催化污水净化性能,可以有效用于水体污染处理.
Abstract
Photocatalytic technology has a good potential in wastewater treatment,but powder catalyst is easy to cause secondary pollution in use.In this paper,graphite phase carbon nitride(g-C3N4)was compounded with polyvinyl chloride(PVC)resin to prepare supported PVC/g-C3N4 photocatalytic composites,and its catalytic performance and stability were studied.The results showed that the loading of g-C3N4 to PVC effectively reduced the agglomeration of g-C3N4 and showed good catalytic performance.The concentration of methyl orange and rhodamine B in PVC/g-C3N4-3 was the lowest after 60 min of illumination,and it showed good stability after 10 cycles.The photocatalytic experiments of different types of sewage show that PVC/g-C3N4-3 composite has good photocatalytic sewage purification performance and can be effectively used for water pollution treatment.
