Antioxidant and Photo Catalytic Activity Of Aqueous Leaf Extract Mediated Green Synthesis Of Silver Nanoparticles Using Passiflora Edulis F. Flavicarpa

The purpose of this study is to minimize the negative impacts of synthetic procedures and to develop environmentally benign procedures for the synthesis of metallic nanoparticles. In the present study, Passiflora edulis. f. flavicarpa (P. edulis) aqueous leaf extract mediated green synthesis of silver nanoparticles are described. The synthesized silver nanoparticles were characterized by UV-Vis Spectroscopy, Fourier Transform Infrared Spectroscopy (FTIR), X-Ray diffraction (XRD), Scanning Electron Microscopy (SEM),) Transmission Electron Microscopy (TEM). The efficacy of the synthesized silver nanoparticles (AgNPs) was demonstrated as catalyst in the photo catalytic degradation of Methyl Orange and Methylene Blue dyes which were measured spectrophotometrically. The study revealed that biosynthesized silver nanoparticles using Passiflora. Edulis f. flavicarpa, plant extract was found to be very effective as antioxidant agent. (C) 2019 Elsevier Ltd.
