Photocatalytic capability of Co۳O۴/g-C۳N۴ nanocomposite in organic dye degradation

A Co₃O₄/g-C₃N₄ photocatalytic nanocomposite was synthesized through a facile co-precipitation method to purify water. Characterization techniques, including X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), UV-vis diffuse reflectance spectroscopy (DRS), and photoluminescence (PL) confirmed the successful integration of Co۳O۴ nanoparticles onto g-C۳N۴ nanosheets. The photocatalytic efficiency was tested by degrading methylene blue (MB) under visible light. Results showed that Co₃O₄/g-C₃N₄ nanocomposite achieved a ۹۳% degradation of MB, significantly higher than Co₃O₄ alone (۳۴%). The enhanced performance is attributed to the optimized band gap energy (۲.۳۲ eV) and efficient charge separation, which accelerate pollutant degradation on the photocatalyst surface.
