ZnO material is seriously limited in the field of photocatalysis application due to its poor stability in acid and strong alkaline solutions. In this study, a ZnO/PVDF core-shell structure membrane (CSM) was prepared by embedding ZnO nanoparticles in PVDF fibers. The obtained ZnO/PVDF CSM was used as a photocatalyst to degrade rhodamine B (RhB) dye. With the increase of ZnO content, the performance of the film increases synchronously, but it shows a saturated trend at high ZnO content. The sample with ZnO content of 9.09 wt% is the best cost-effective. In an acidic solution, the degradation efficiency of ZnO/PVDF CSM was 100 % under Xe lamp irradiation for 60 min may be caused by the acid induced decolorization effect. The membrane after acid and alkali treatment could still degrade RhB normally, and had good acid and alkali resistance. Due to the piezoelectric coupling effect between ZnO and PVDF, the photo-generated holes (h+) can transport onto the surface of PVDF nanofiber, accomplishing the photocatalytic reaction. The obtained ZnO/PVDF CSM also exhibits good recyclable performance with high stability. In addition, ZnO/PVDF CSM can also be used for water-in-oil separation. This work provides a promising strategy for the development and improvement of ZnO based composite material in acid solution.
