Study on Catalytic Reduction of Methylene Blue Using Silver Nanoparticles Synthesized via Green Route

Abstract

Abstract: We have synthesized silver nanoparticles using silver nitrate and Azadirachta indica (Neem) aqueous leaf extract at room temperature. The method used for synthesis is simple, rapid, environmental free and do not involve toxic chemicals. The terpenoids and flavonoids available in neem plant leaf extract act as both capping and reducing agents. The synthesized nanoparticles are characterized UV Visible spectroscopy, X ray diffraction analysis and fluorescence spectroscopy. The synthesized AgNPs are used for study of the catalytic degradation of methylene blue by sodium borohydride (NaBH4) in presence of AgNPs as catalyst. The 100% degradation of methylene blue was achieved by (NaBH4+AgNPs) in just 08 minutes which highlights the efficient catalytic activity of AgNPs.
