Abstract Single ZnO (NM1), MnO 2 (NM2) nanoparticles, and –g‐C 3 N 4 –ZnO (NM4) nanocomposite were synthesized by the sol–gel method, whereas g‐C (NM3) was polymerization of urea. The as‐synthesized materials characterized thermogravimetric‐differential thermal (TGA‐TDA), Fourier transformer (FTIR), X‐ray diffraction (XRD), diffuse reflectance spectroscopy (DRS), scanning electron microscopy (SEM), high‐resolution transmission (HRTEM).The bandgap NM4 lower than those NM1, NM2, NM3 photocatalysts, which is applicable in visible region. photocatalytic activities studied under light radiation. efficacy composite 5, 3.4, 3‐fold higher materials. This enhancement might be ascribed to synergistic effect. Besides, degraded 94% methylene blue (MB) 81% real sample. rate constant ( k ) for NM3, also resulted 0.00327, 0.0046, 0.0056, 0.0156 min −1 , respectively. reusing carried out four sequential rounds 94%, 92.6%, 91%, 89% degradation efficiency 1st, 2nd, 3rd, 4th round, result suggests that cost‐effective stable.
