Preparation and photocatalytic properties of self-supporting polyacrylonitrile/Cd0.8Zn0.2S/MgIn2S4 nanofiber membrane
Polyacrylonitrile(PAN)/Cd0.8Zn0.2S/MgIn2S4 composite nanofiber membrane was prepared by electrospinning and solvothermal methods.The crystal structure,optical properties and morphology of the samples were characterized by DRS,SEM,XRD and electrochemical measurements.The photocatalytic activity of PAN/Cd0.8Zn0.2S/MgIn2S4 composite nanofiber membrane was investigated by simulated visible light-driven photodegradation of rhodamine B.Compared with PAN/Cd0.8Zn0.2S and PAN/MgIn2S4,PAN/Cd0.8Zn0.2S/MgIn2S4 composite nanofiber membrane exhibited the best photocatalytic degradation performance,with a degradation efficiency of 96％at 120 min.The as-prepared PAN/Cd0.8Zn0.2S/MgIn2S4 composite nanofiber membrane has good flexibility and self-supporting properties compared with powdered semiconductor photocatalysts.It is easy to recover in practical applications and can avoid secondary pollution.
