Abstract

Sustainable synthesis of metallic nanoparticles has ensnared the world from the chemical and physical slants owing to its rapid, harmless, and pecuniary trait of production mechanism.  The present study demonstrates green synthesis of CoONPs using petal extract of temple wastes of pink rose (ROR), red rose (RER), yellow rose (YOR), and orange roses (ORR).  To date, there is no reporton the synthesis of CoONPs utilizing an aqueous flower extract of these four rose petals.  In this research work, four rose flowers petal extract in a concentrated solution of cobalt nitrate hexahydrate in CoONPs. Cobalt nitrate hexa hydrate was reserved as the metal precursor, whereas flower extract act as a reducing and stabilizing agent.  The phytochemicals present in the extract act as reducing agents, which include saponins, phenolic compounds, and flavonoids.  Phyto-constituents and CoONPs stretching and bending vibration are measured by FTIR spectroscopy, FL spectrum was also done to study the fluorescence activity of cobalt nanoparticles with four different rose petal extracts, Morphology of the cobalt nanoparticles were designed by scanning electron microscope (SEM), and the particle size are measured by dynamic light scattering (DLS) analysis. Finally, the electrochemical properties of CoONPs were studied by cyclic voltammetry (CV) with impedance spectrum.
