“…[ 58–63 ] GO and its analogs are used to catalyze various organic transformations (Table 1). In 2019, Gupta et al [ 5 ] thoroughly reviewed the applications of GO in the synthesis of several heterocyclic scaffolds and various organic transformations. Recently, Jay et al [ 64 ] synthesized biscoumarin derivatives by GO as a catalyst in high to excellent yields in a short period of time (Scheme 1).…”

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.

“…Among those carbocatalysts graphene oxide (GO) considered as one of the most popular catalyst due to its 2D-structure, facile decoration, large surface area, excellent heat conductivity, very good light transmittance, high adsorption capacity, exceptional electron conductivity, easy to functionalization and chemical inertness. [4][5][6][7][8][9] MOreover GO is very easily recoverable and reusable and have no environmental hazard issues. That's why in green and sustainable view-points the graphene oxide is very precious carbocatalyst in various organic transformations.…”

A 2-Dimensional sp 2 -hybridised carbon based material graphene oxide (GO) was synthesized and characterized by various instrumental techniques viz. FTIR, PXRD, Raman, FESEM and HRTEM. The metal free environmentally benign carbocatalyst was fruitfully used as catalyst for the synthesis of primary carbamates from alcohols in presence of non hazardous cheap carbonyl source urea. Both aromatic (bezylic as well as phenolic) and aliphatic alcohols produced moderate to very high yield (53-95 %) of corresponding carbamates through this catalytic reaction. The used GO catalyst is very straightforward to recover from reaction mixture via centrifugation method. The heterogeneous and reusability nature of the catalyst exists several cycles of catalytic reaction. We check six cycles of the catalytic reaction and the activity of the catalyst after 6 th cycle does not alter very significantly.

“…Despite excellent research on the use of graphenebased heterogeneous catalysts in organic transformations of simple and complex molecules [18,20,34], there are only a few literature reports [61][62][63] related to the investigations based on the use of GO/rGO as a catalyst/ catalyst support for the green synthesis of biologically relevant molecules. The use of a number of oxygenated groups in particular, viz.…”

Graphene is considered a promising catalyst candidate due to its 2D nature, single-atom thickness, zero bandgap and very high surface to volume ratio. Further, graphene oxide (GO) has been used as a catalytic support material for metal/metal oxide nanoparticles due to its tunable electrical properties. In addition, its high chemical stability and ultrahigh thermal conductivity may possibly promote high loading of catalytically active sites. This review article focuses on the recent progress in the catalytic applications of GO especially (i) as catalytic-support material (GO/reduced graphene oxide supported metal/metal oxide nanohybrids) for the green synthesis of biologically relevant molecules, (ii) for metal-free catalysis and (iii) for electrocatalysis, with special focus on graphene contribution to catalytic efficiency. The critical overview and future perspectives are also discussed.
