“…A modi-ed Hummers and Offeman's method was used to fabricate the GP nanosheet from natural graphite powder. 47,48 8 g of graphite powder (Sigma-Aldrich) and a stoichiometric amount of NH 4 NO 3 were added to 368 ml of 98% (w/w) H 2 SO 4 in an ice bath. KMnO 4 was slowly added to the mixture with continuous stirring until the solution turned green.…”

“…It was observed that newly fabricated GO-Fe 3 O 4 (3.66 eV) and GO-Fe 3 O 4 @ZrO 2 (3.20 eV) nanocomposites have the advantage of smaller bandgaps than GO (4.00 eV), which result in increased adsorption capacity and photocatalytic effects. Results confirmed that RhB is efficiently adsorbed over the surface of graphene oxide (~93%) and has a significant inhibitory effect against E. coli bacteria [51].…”

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.

In the last decades, heterogeneous catalysis has emerged as a promising approach for sustainable synthesis. Among this, metal‐based graphene oxide (GO) as catalysts is widely used due to their unique properties such as physical and thermal stability of the catalysts in successive reaction runs and reusability. Metal‐supported GOs are quite prevalent and probably suitable acidic catalysts for both research laboratories and industrial processes. Herein, we have described the catalytic efficiency of various metal‐supported GO catalysts in different organic transformations like oxidation, reduction, multicomponent reactions, alkylation, condensation, dehydration, dehydrogenation, and Suzuki, Heck, and Sonogashira reactions. This article has been divided into three subsections: (i) GO‐supported metal as a catalyst, (ii) GO‐supported bimetal as a catalyst, and (iii) GO‐supported metal oxide as a catalyst for the easier understanding of the vast community of researchers. The foremost aim of this article is to summarize the uses of metal‐supported GO in the preparation of diverse synthetic molecules. The recent advancements in GO metal composites as catalysts with their applications have been deliberated.
