Nanomaterials: Green Synthesis for Water Applications

Abstract

Future environmental applications require the integration of green and sustainable nanomaterials. Hence, this chapter highlights the basics of nanotechnology and summarizes the synthesis of green nanomaterials compared to the conventional routes of nanomaterials. Nano-characterization techniques have been classified to identify/confirm the synthesized nanomaterials. A comprehensive overview about zerovalent metal nanomaterials, metal-based nanomaterials, carbonaceous nanomaterials, and nanocomposites is explored. The optimum parameters and conditions are studied. Furthermore, green synthesis mechanisms of some nanomaterials are discussed. Subsequent to an overview of various green nanomaterials, their integration for various pollutants' removal is presented.
