BIOSYNTHESIS AND CHARACTERIZATION OF GOLD NANOPARTICLE FROM COCCINIA GRANDIS AND ITS CATALYTIC ACTIVITY
Journal Title: International Journal of Pharmaceutical Sciences and Research (IJPSR) - Year 2019, Vol 10, Issue 9
Abstract
The fabrication of spherical gold nanoparticles (AuNPs) using the reducing agent and stabilizing agent Coccinia grandis is reported here. Irradiation of the reaction mixture under a domestic microwave oven enabled the formation of gold nanoparticles. The successful formations of AuNPs were characterized by UV-Visible spectroscopy (UV-Vis), Fourier transforms infrared spectroscopy (FTIR), X-ray powder diffraction and transmission electronic microscopy (TEM). Chemical components are inherent in the leaf extract which reduces the gold were identified using FTIR Spectra. The crystal structure of the AuNPs was established as a face-centered cube by the Powder XRD analysis. TEM results suggested that under optimized synthetic conditions monodispersed and spherical nanoparticles with an average diameter of 10 ± 2 nm could be achieved. The nanoparticles effectively showed catalytic activity for the reduction of environmental pollution causing methylene blue dye. The study concludes that the synthesized nanoparticles could be considered as environmental protectants due to its potent catalytic activity.
