**4. Conclusion**

In this chapter, we have reviewed the inherent carbocatalytic activity of graphene oxide towards different organic transformations. The π-π\* network as well as oxygenated functional groups present over the GO surface both contributed towards the enhanced catalytic activity. The presence of π-π\* network on graphene surface helped the substrate molecules getting adsorbed over the catalyst surface and the oxygenated functional groups catalyzed the reaction. The oxygenated functional groups acted as the active site for several acid catalyzed as well as oxidation reactions. Further, the presence of various oxygenated functionalities on the surface of graphene oxide could be used for anchoring other active catalysts such as metal and metal oxide nanoparticles. The reducing capability of these nanocarbons could also be envisaged for reduction of metal ions to nanoparticles.
