ABSTRACT

Nowadays nanoparticles play an important role from biomedical to household. Therefore synthesis of eco-friendly nanoparticles is evergreen branch of nanoscience for biomedical application. Low cost of synthesis and non toxicity are main features of green synthesis of nanoparticles which make it more attractive potential option for biomedical field. Nanotechnology has dynamically developed as an important field of modern research with potential effects in electronic and medicine.[1] The present study reported a fast, green and simple method for reduction of silver nitrate to elemental silver from the Semecarpus anacardium Linn.F leaf aqueous extract. The confirmation of silver nanoparticles was done by uv-visible spectrophotometer. The structure of AgNps was confirmedy X Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) EDX techniques. A detailed study of kinetic aspect of silver nanoparticles with respect to temperature and time were investigated. The catalytic activity of AgNps was investigated by selecting the reduction of 4-nitrophenol to 4- aminophenol using aqueous NaBH4 as reducing agent.
