GREEN SYNTHESIS AND CHARACTERISATION OF COPPER OXIDE NANOPARTICLES USING PSIDUM GUAJAVA LEAF EXTRACT

Abstract

Green synthesis of nanoparticles has gained enormous attention in today’s world due to ongoing demand to develop sustainable, safe, economical and eco-friendly process for synthesizing a wide variety of materials including metal/metal oxides nanoparticles, hybrid and bioinspired materials. In the current study, green synthesis of copper oxide (CuO) nanoparticles (NPs) has been carried out by utilising extract of psidium guajava leaf as capping agent and cupric acetate as metal precursor. The biosynthesized nanoparticles were characterized utilizing wide assortment of methodologies for example powder X-beam diffraction (PXRD), FTIR, TGA and HRTEM. The PXRD result confirms the synthesis of CuO NPs in pure phase having monoclinic symmetry. The average particle size using PXRD was found out to be ~33nm
