STUDY STRUCTURE AND THE PHOTOCATALYTIC ACTIVITIES DEGRADATION OF RHODAMINE B ON ZnO/g-C3N4/PVDF MEMBRANE MATERIAL

Abstract

ZnO/g-C3N4 composites were loaded onto a polyvinylidene fluoride (PVDF) membrane using a phase
inversion method to obtain a photocatalytic flat membrane for Rhodamine B(RhB) dye removal. Material
properties were studied by modern physicochemical methods of X-ray diffraction (XRD), infrared
spectroscopy (FT-IR), scanning electron microscopy (SEM), and photoluminescence (PL) spectrum. XRD
and FT-IR studies confirmed the incorporation of ZnO and g-C3N4 into the PVDF substrate. In addition, the
hetero-structures formed between ZnO and g-C3N4 nanosheets promoted the separation of photogenerated
electron-holes in the g-C3N4 layer. They improved the photocatalytic and anti-fouling performance of the
ZnO/g-C3N4/PVDF composite. The photocatalytic activity of the materials was evaluated through the RhB
dye degradation reaction under visible light, resulting in the ZnO/g-C3N4/PVDF composite film with the
highest efficiency (90.00%). Therefore, this research is expected to be extended to environmental treatment.
