Carbon Based Nanomaterials for Wastewater Treatment

Abstract

The global water scarcity and the deterioration of water quality have raised an alarming concern. Nanomaterial based remediation provides a remarkable potential to address the challenges posed by conventional approaches. Carbon based nanomaterials such as carbon nanotubes, graphene and its derivatives, graphitic carbon nitride, nanodiamonds, fullerenes, porous carbon, carbon and graphene quantum dots have been extensively explored for wastewater treatment. This chapter aims to focus on the recent developments in the rational designing and application of various carbon based nanomaterials for wastewater treatment and remediation through adsorption and photocatalysis. Functionalization and surface modification of these materials to meet the desired outcome by stringent modulation of the physicochemical properties have also been discussed. This would provide state-of-art and delve into the background that would assist the researchers in exploration of these materials for fabrication and designing of novel nanocomposites for removal of toxic pollutants from wastewater.
