Organic dye degradation over g-C۳N۴/ZnO nanocompositephotocatalyst under visible light irradiation

A practical g-C₃ N₄ /ZnO nanocomposite photocatalyst was prepared via a simple chemical method. Variouscharacterization techniques were employed such as X-ray diffraction (XRD), field emission scanning electron microscopy(FESEM), UV-vis diffuse reflectance spectroscopy (DRS), and photoluminescence (PL) verifying the effective loading ofZnO nanoparticles on the g-C₃ N₄ nanosheets. Methylene blue (MB) dye was used to investigate the photocatalyticactivity of the synthesized samples under visible light irradiation, where the g-C₃ N₄ /ZnO nanocomposite achieved a۹۷% degradation rate, significantly higher than ZnO with ۶۴%. This enhanced activity could be due to the efficientcharge separation, promoting faster pollutant degradation.
