Degradation of organic dye by g-C3N4-CuO nanocomposite photocatalyst fromwastewater abstract
Removing pollutants such as organic dyes has become a critical challenge and can be degraded usingphotocatalysts. In this study graphite carbon nitride (g-C3N4), pure copper oxide (CuO), and g-C3N4-50wt.%CuO nanocomposite were synthesized through a chemical method. Several techniques havebeen used to characterize the prepared samples. X-ray diffraction (XRD) results confirmed that thesynthesized nanocomposite consists of g-C3N4 and CuO phases. The results of field emission scanningelectron microscopy (FESEM) showed that CuO particles are placed on g-C3N4 nanosheets. The opticalband gap energy of 2.3 eV was estimated by diffuse reflectance spectroscopy (DRS). The photocatalyticperformance of the synthesized compound was evaluated on methylene blue (MB) dye. Degradationtests were performed for 180 min under visible light irradiation. The highest degradation rate wasobtained over g-C3N4-CuO nanocomposite.
