| 摘 要： | 为提高石墨相氮化碳(g-C3N4)的光催化性能,采用3D花状ZIF-Co与g-C3N4混合热处理的方法制备了3D花状Co3O4/g-C3N4复合光催化剂,并将其用于光催化降解罗丹明B模拟染料废水。结果表明:当ZIF-Co与g-C3N4的质量比为5%时,制备的Co3O4/g-C3N4的光催化性能最佳,在可见光下照射30 min,其对罗丹明B的降解率可达90%以上,且该催化剂的重复稳定性好。在降解罗丹明B的过程中活性基团的作用顺序为·O2->h+>·OH。

| Abstract: | To further improve the photocatalytic activity of g-C3N4,3D flower-like Co3O4/g-C3N4 were prepared via calcining the mixture of 3D flower-like ZIF-Co and g-C3N4.The prepared composite photocatalyst was used for the degradation of Rhodamine B(RhB)simulated wastewater.The results showed that above 90%of RhB can be removed in 30 min under visible light irradiation by the Co3O4/g-C3N4,when the mass ratio of ZIF-Co to g-C3N4 was 5%,which exhibited the best photocatalytic performance.In addition,the catalysts showed good stability.Besides,the role of radicals in RhB degradation followed the sequence:·O2->h+>·OH. |
