Green Synthesis of Metal Nanoparticles

Abstract

In the last two decades, metal nanoparticles have been created much interest among the scientists due to its application in different field such as sustainable energy, food safety, environmental science, catalysis, medicine etc. The synthesis of the metal nanoparticles in the chemical method involves large energy consumption, environmental pollution which leads to health problems. The green synthesis of metal nanoparticles using plant extract as the reducing agent are more beneficial than the chemical methods due to low cost, environment friendly, health safety. In this review, green synthesis of Ag NP, Au NP, Pd, Pt NP and their applications are discussed.
