With the use of facile single-step calcination Zinc glutamate MOF and melamine, highly efficient ZnO/g-C3N4 nanocomposite was prepared utilized in photocatalytic degradation Rhodamine B (RhB), an organic pollutant. The composite's morphology, crystallinity, optical properties, composition were determined using several analytical techniques, which include scanning electron microscopy (SEM), transmission (TEM), Fourier-transform infrared (FTIR) spectroscopy, X-ray powder diffraction (XRD), diffuse reflectance spectroscopy. RhB over optimized 1.0%ZnO/g-C3N4 composite is ∼1.77 fold higher compared to pure g-C3N4 under identical conditions. synergistic interfacial interaction between derived ZnO remarkably improved electron-hole pairs separation, led exceptionally high activity photocatalysts. Based on radical scavenger tests ESR analysis, it confirmed that •O2− as dominant active specie facilitated as-prepared composites. This work will open up new insights for further research based materials.
