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

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 photocatalytic degradation efficiency of carbaryl and imidacloprid was 22 and 92.6% in the presence of GO@TiO 2 whereas 7 and 56.6% in the presence of TiO 2 alone. It suggests the superiority of GO@TiO 2 nanocomposite over TiO 2 NPs for degradation of the examined toxic insecticides [77] .
