Annotation
In this study, an O-g-C₃N₄/ZnO nanocomposite was synthesised via thermal polycondensation of melamine, followed by modification with zinc oxide derived from secondary zinc wastes. Structural identification and thermal properties of the obtained material were systematically investigated. Fourier-transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) confirmed the coexistence of two crystalline phases and interfacial interactions within the composite. Comprehensive thermal analysis revealed that the material exhibits high thermal stability up to approximately 400 °C and an energy-intensive thermal degradation process. The calculated kinetic and thermodynamic parameters indicate that the synthesised composite can be applied in high-temperature photocatalytic and wastewater treatment systems.
