Carbocatalytic Activity of Graphene Oxide in Organic Transformations: A Comprehensive Review

This review article provides a detailed summary of the current advances in the field of heterogeneous catalysis using graphene oxide. The applications of graphene oxide have received a lot of attention over the past few years. The simple synthetic protocols and their green chemistry approach have increased the popularity of novel nanocatalysts. Because of its unique properties, graphene oxide (GO) has become one of the most fascinating and extensively studied materials. Scientists have found a variety of inimitable optical, electrical, and chemical characteristics in graphene oxide which can be utilized in diverse applications. Graphene oxide as a 2D framework adorned with oxygen-containing functional groups possesses rich chemical properties and may present a green alternative to precious metal catalysts. The catalytic organic transformations extensively use graphene oxide (GO) as a metal-free and easily accessible carbocatalyst. This article primarily discusses the synthesis of GO and its utilization in reactions involving oxidation such as oxidative coupling and oxydehydrogenation reactions, functional group modifications, such as the oxidation of hydroxyl (& horbar;OH) group and boronic acid, oxidative halogenations, Friedel-Crafts reactions, condensation reactions, and other reactions.
