[Display omitted] • NiVCuO/C 60 nanocomposites synthesized for the first time by solution method. • Recent advances in properties modified with fullerene were discussed. • Excellent photocatalytic application modified with fullerene. • Tuning the band gap and surface of the NiO catalyst. • Degradation of dyes (MB, RhB, SO, and CR) dye more efficiently. 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 (C 60). 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/C 60 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/C 60 has degradation efficiency of 99.5, 98.6, and 75% towards SO, MB, and CR dyes, respectively. The fabricated NiVCuO/C 60 nanocomposite achieved the high degradation required for practical application. [ABSTRACT FROM AUTHOR]
