Reduction of 4-nitrophenol Mediated by Silver Nanoparticles Synthesized using Aqueous Leaf Extract of Peronema canescens

Abstract

In this study, we developed an alternative of 4-nitrophenol reduction mediated by silver nanoparticles (AgNPs) which was synthesized using aqueous extract of the Peronema canescens leaf through an eco-friendly approach. The reducing 4-nitrophenol to 4-aminophenol mediated by AgNPS in the presence of sodium borohydride as a hydrogen source proceeded rapidly at room temperature without any additional treatments. The AgNPS synthesis was simple and was carried out under mild conditions. Ultraviolet–visible spectroscopy was performed to examine the properties of the obtained AgNPs, which displayed an absorption peak at 431 nm. A transmission electron microscopy analysis revealed that the AgNPs were spherical in shape and had an average particle size of 19 nm as determined by particle size analysis.

Evaluation of Peronema canescens Leaves Extract: Fourier Transform Infrared Analysis, Total Phenolic and Flavonoid Content, Antioxidant Capacity, and Radical Scavenger Activity

“…This phytochemical screening was carried out to qualitatively identify certain secondary metabolite compounds from the ethanolic extract of the leaves of P. canescens (Table 1). Phytochemical screening is also one of the steps of the method used to explore antioxidant compounds in various plants [19] P. canescens leaves (alkaloids, flavonoids, terpenoids, steroids, and tannins) are thought to play an important role in certain biological responses of P. canescens plants [21]. The presence of positive flavonoid and tannin compounds is a natural antioxidant with free radical scavenging activity.…”
