Ipomoea quamoclit L. Leaf Extract Assisted Synthesis of Silver Nanoparticles: Study of its Application on Catalytic Degradation of Dyes and Antibacterial Efficacy

Abstract

Recently nanoparticles have been widely used in various applications such as antimicrobial, drug delivery, catalysis, sensors and screening of toxic organic and inorganic pollutants. Here we present an environmentally friendly, simple approach and an efficient approach for the green synthesis of silver nanoparticles using Ipomoea quamoclit L. leaf extract. In this work, a novel method for green synthesis of silver nanoparticles-based Ipomoea quamoclit L. plant extract as green reducing agent is described. The morphological and optical properties of the nanoparticles were characterized by XRD, FT-IR, HR-SEM, TEM and UV-visible spectrum. The silver nanoparticles prepared from Ipomoea quamoclit L. had a size range from 20 nm to 50 nm as observed by the FE-SEM analysis. The XRD pattern revealed the crystallinity nature of the prepared silver nanoparticles. Stable silver nanoparticle solution has been synthesized using Ipomoea quamoclit L. leaf extract under the optimized experimental conditions. This silver nanoparticle can be used as a catalyst for degradation of textile dyes. The resulting reaction follows pseudo-first-order kinetics. The silver nanoparticles exhibited a moderate antibacterial activity towards Bacillus subtilis and Salmonella sp. had an inhibition zone of 34 mm and 20 mm, respectively.
