Abstract
Carbon dots (CDs), owing to their zero-dimensional structure and outstanding physicochemical features, can be used as a support to metals, metal oxides, to form nanocomposites, thus emerging as promising nanocatalysts to drive various organic transformations. For this reason, we planned to review the usage and advantages of these carbon dots and their supported catalysts, in various organic reactions. Furthermore, the recent advancements in CDs to develop it as an amphiphilic catalyst to use an environmentally benign solvent (water) to solvate organic reactants in organic reactions have also been discussed.
