Ionic Liquid-Assisted Fabrication of ZnO with Enhanced Photocatalytic Performance

Abstract:

In this paper, ZnO photocatalyst was prepared by sol-gel method with the assistance of ionic liquid (IL). The structure, morphology and the photoinduced charge separation rate of the photocatalyst prepared (IL-ZnO) were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and surface photovoltage spectroscopy (SPS), respectively. The results reveal that ionic liquid enhances the photoinduced charge separation rate. The activity of ZnO for photocatalytic decolorization of methyl orange (MO) solution was evaluated. The results show that the photocatalytic activity of IL-ZnO is higher than that of ZnO.
