N2 - NiO act as an efficient photocatalyst, and an appropriate design is necessary to support simultaneous highest photon absorption and lower charge carrier recombination. In this study, V/Cu were co-doped in NiO nanoparticles and then coupled with fullerene (C60). X-ray diffraction and FTIR spectroscopy are used to investigate the structural variations. Further characterization tools were used to disclose the origin of surface imperfections inside the nanostructures, including Raman, UV, and PL spectroscopy. XPS was employed to examine the chemical composition of Ni, Cu, V, and C. EDX confirmed the elements in NiVCuO/C60 composition. These imperfections decrease the charge carrier recombination and improve photocatalytic degradation (∼99.8%) of RhB dye, with a rate constant ∼0.042 min−1 under sunlight exposure. In addition, NiCuVO/C60 has degradation efficiency of 99.5, 98.6, and 75% towards SO, MB, and CR dyes, respectively. The fabricated NiVCuO/C60 nanocomposite achieved the high degradation required for practical application.
