Abstract

Abstract: Nanomaterial synthesis using a greener route has received massive attention as a sustainable, feasible, reliable, cost-effective, wealthy and environmentally friendly paradigm. Perhaps, synthesis via a greener route is considered as a sophisticated tool to minimize the toxic effects agglomerated with the conventional procedures of synthesis adapted for nanomaterials generally preferable in industry and laboratory. This work outlines the basic processes on the advanced patterns of the eco-friendly and various approaches involved in the green synthesis and its mechanism particularly accounted to metal and metal-based oxides like silver (Ag), gold (Au), zinc oxide (ZnO) and copper oxide (CuO) nanoparticles with the aid of plant extracts. This review article encompasses the essential purpose of biological approaches, green roué for nanoparticle synthesis, the impact of various operating parameters, and solvent-based techniques. The toxicity/stability of nanomaterials and the occluded surface engineering protocols for deriving biocompatibility along with various solvent systems have also been outlined. Various mechanisms involved for green synthesis, merits of greener chemistry and its application in various fields are emphasized. Finally, the prospects of green route strategies for metal/metal oxide nanomaterials synthesis are proposed for further development. The challenges in utilizing the green synthesized metal/metal oxide nanoparticles are discussed. The recommendations of the green chemistry towards the cleaner production are emphasized.
