In the recent years, plant and microbial extract based nanoparticles (NPs) have become a sophisticated technology serving as an alternative strategy for the purpose of developing materials functionalized by structural diversity and enhanced energy efficiencies. Cobalt oxide nanoparticles (GCoO-NPs) have wide applications in several sectors due to their high resistance to corrosion as well as oxidation, ecofriendly nature, cost effectiveness and nontoxic potential. Plant based particles are credible alternatives as they reduce the burden of complicated and laborious protocols of physiochemical reliance. In this study, GCoO-NPs were synthesized using the grape Jumbo Muscadine (Vitis rotundifolia) using co-precipitation. The synthesized GCoO-NPs were characterized by UV–Vis spectrophotometer, Fourier transform infrared spectroscopy (FTIR), Powder X-ray diffraction (PXRD) and Scanning electron microscopy (SEM). The photocatalytic activity of the GCoO-NPs was estimated by the degradation of Acid Blue-74 (AB-74) dye and the complete degradation of 98% was accomplished at the reaction time of 150 min at pH 10 and 60 mg/100 mL concentration. The outcomes of this study indicated the excellent performance of the GCoO-NPs on par with some of the earlier findings and this can be an appealing aspirant of extreme potential to be employed as a catalyst alternative to the conventional wastewater treatment methods. •First report on the synthesis of Cobalt oxide nanoparticles (GCoO-NPs) Jumbo Muscadine (Vitis rotundifolia)•GCoO-NPs have been characterized by UV–visible, FTIR, XRD and SEM analysis•Photocatalytic activity of GCoO-NPs was estimated by degrading Acid Blue-74 (AB-74) dye.•Dye degradation (98%) was accomplished at 150 min, pH 10 with 60 mg/100 mL concentration.
