Preparation of PVC/g-C3N4 Composites and Its Photocatalytic Purification of Wastewater
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.
