Graphene- and Graphene Oxide-Bounded Metal Nanocomposite for Remediation of Organic Pollutants

Abstract

Nanotechnology is one of the most interesting areas concerned with consumer products including cosmetics, household appliances, electronics, textiles, and food production as well as in medical products. Environmentally benign, economical, practical, and efficient processes for the synthesis of graphene (rGO)-/graphene oxide (GO)-bounded metal nanoparticles and their use for the remediation of organic pollutants (dyes, pharmaceutical wastes, pesticides, etc.) have been increasingly important goals in the chemical community from economic, safety, and environmental points of view. In this chapter, various strategies have successfully demonstrated the synthesis of graphene-/graphene oxide-bounded metal nanoparticles using various natural sources (plant extracts, biomolecules, polysaccharide, alcohols, etc.) and their applications in environmental remediation.

The Impact of Green Technology on Sorption Processes

“…Nanomaterials are tiny particles that have unique structural and chemical properties, which make them highly effective in the removal of contaminants. One example of such material is graphene oxide [51], which has shown great potential for the removal of organic pollutants from wastewater. The use of nanomaterials is also beneficial as it reduces the amount of sorbent needed, thus reducing waste generation.…”

Green Methods of Chemical Analysis and Pollutant Removal

“…AOPs are considered powerful methods for degradation of various organic pollutants due to their ability for removing almost any organic contaminant. A great number of methods are classified under the broad definition of AOPs based on the oxidizing agents applied [32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50].…”

“…Several metal [48] and metal oxide nanomaterials including iron oxide [49], graphene oxide [48], as well as graphene bounded with metals [50] have shown strong oxidizing power. Iron oxide nanoparticles have been prepared by using citrus extract for confinement of the particle growth.…”

“…Iron oxide nanoparticles have been prepared by using citrus extract for confinement of the particle growth. This method has produced in the nanoparticles providing a larger surface, an advance to result in effective degradation of some dyes [49]. The nanocomposite of graphene oxide bound with metal by using biomass as a template has also been reported [48].…”
