Abstract
Nowadays, the use of carbocatalyst has attracted much attention due to its sustainability and affordability. Graphene oxide (GO) and sulfonated graphene oxide (SGO) have emerged as environmental friendly, metal free, inexpensive carbocatalyst for the synthesis of organic compounds. Herein, the profound role of GO and SGO in different organic transformation has been established. The GO and SGO being heterogeneous in nature, have high thermal stability over homogeneous catalyst in successive runs and can easily be recovered. The presence of oxygen containing acidic groups in GO and SGO mainly catalyzes the organic reactions. This mini review is emphasized on the catalytic role of GO and SGO as green and reusable solid acid catalyst in different organic syntheses.
Keywords: Graphene oxide, sulfonated graphene oxide, carbocatalyst, green synthesis, organic transformation, KMnO4, ultrasonication, sulfanilic acid.
