Abstract
Photocatalytic PVDF-ZnO/Ag2CO3/Ag2O mixed matrix membranes (MMM) were prepared by wet-phase inversion method. Incorporating the ZnO/Ag2CO3/Ag2O photocatalyst into the membrane surface resulted in a more hydrophilic membrane surface. The PVDF-ZnO/Ag2CO3/Ag2O membrane exhibited remarkable ability on pure water flux filtration under visible light irradiation due to the photoinduced hydrophilicity of ZnO/Ag2CO3/Ag2O. Thus, when pure water is filtered under visible light (photo-filtration), the flux found slightly higher than flux in the dark. Apart of that, membranes with higher loading of ZnO/Ag2CO3/Ag2O photocatalyst, have higher flux increment during light irradiation. The highest loading of ZnO/Ag2CO3/Ag2O photocatalyst showed the highest PWF increment up to ~9.81% after 180 min of light irradiation. Throughout this study, the excellent performance of PVDF-ZnO/Ag2CO3/Ag2O membrane provided valuable insight for photocatalytic membrane application in water production field.
