Green synthesis of zinc oxide nanoparticles (ZnO-NPs) is a novel and non-toxic process that replaces harmful existing physical and chemical methods. The synthesized nanoparticles with C.reticulata peel powder were characterized with visual analysis, UV-visible spectroscopy and PSA for nanoparticle confirmation. The maximum UV-visible spectral absorption peaks were observed in aqueous extract 357 nm compare to ethanol extract 340.2 nm wavelengths. Aqueous extract showed greater particle size with 55 nm, whereas the particle size in ethanol extract was found to with 75.8 nm with ZnO-1 precursor. Similarly, an average particle size of 76.7 nm in aqueous extract was observed in ZnO-2 precursor, whereas in ethanol extract it is 82.2 nm. As a result of the experimental study, water has been identified as an universal, safe, and environmentally friendly solvent with an optimal and acceptable solvent system for green synthesis of zinc oxide nanoparticles.
