Tea Plant Leaves for Green Synthesis of Metallic Nanoparticles

Abstract

AbstractSynthesis of metallic nanoparticles using tea plant leaves is a well‐recognized and non‐toxic method. During the last few decades, synthesis of metal nanoparticles using plant extract is useful not only because of its reduced environmental but also because it can be used to produce large quantities of nanoparticles. Plant extracts may act both as reducing agents and stabilizing agents in the synthesis of nanoparticles, this has motivated the researchers to synthesis the nanoparticles using this route that allows better control of shape and size for various applications. This paper reviews the methods of synthesizing by using metals (e.g., gold [Au], silver [Ag], Iron [Fe], Cadmium [Cd], Palladium [Pd], copper [Cu]), nanoparticles from tea plant leaves extracts as well as their characteristics and some applications. The aim of this review is to report the effect of tea extraction for synthesis metallic nanoparticles (NPs) and compare the nanoscale properties and its applications.
