Abstract : To combat the growing issue of dye contamination in wastewater, developing high-performance photocatalysts is essential. This research details the fabrication of cobalt oxide–graphitic carbon nitride (Co₃O₄/g-C₃N₄) nanocomposites, achieved through a straightforward, single-step pyrolysis process utilizing urea as the g-C₃N₄ precursor. Comprehensive material characterization was conducted using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and energy-dispersive X-ray spectroscopy (EDX). The resulting data verified successful cobalt oxide integration, a crystalline framework, and a unique flower-like structural morphology featuring a mean crystallite size of 89.14 nm. The performance of the fabricated nanocomposite was tested by measuring how effectively it breaks down Crystal violet dye under visible light. During this evaluation, the team systematically adjusted key variables, including light intensity, catalyst amount, initial dye concentration, and pH levels. The results revealed that the composite performs significantly better than either pure cobalt oxide or standalone g-C₃N₄. This boosted efficiency stems from a clear synergistic interaction, which improves charge separation and strengthens interfacial contact. Consequently, these outcomes highlight the potential of Co₃O₄/g-C₃N₄ nanocomposites as highly effective agents for eco-friendly wastewater treatment.
