| Abstract: | Graphene oxide and bismuth vanadate sol are successively loaded onto cotton fabric,and the functional fabric loaded with bismuth vanadate/graphene is obtained by UV reduction.Taking Reactive Black KN-B as the degraded object,the catalytic activity of functional fabric under visible light is studied.The influence of dye structure on photocatalytic effect is discussed.The results show that the degrada?tion rate of functional fabric to 20 mg/L Reactive Black KN-B solution is more than 95%after 120 min of visible light irradiation,and the degradation rate can still exceed 80%after repeated use for 5 times.The degradation rate of functional fabric depends on chemical structures of the dyes. |
