The discovery of C60 has opened a new epoch for the study on nanomaterials. Using C60 as a precursor, a suspension of carbon quantum dots can be synthesized with high yield, narrow size distribution and good dispersion in water. Furthermore, a controllable doping and assembly to the C60-derived quantum dots may lead to novel carbon electrodes with superior supercapacitor performances, targeting for the balance between volumetric performance and electrode density in carbon-based supercapacitors. Focusing on the issues of production yield, controllability in size and microstructure, and introduction of defects and doping in the preparation of carbon quantum dots and assembly, the current study will develop chemical synthesis methods to achieve novel carbons with controllable structures, doping and defects, taking advantages of pentagons and curvatures in C60 molecules. In addition, advanced tools such as synchrotron radiation will be utilized to characterize the electronic and interface properties, towards a series of carbon materials with high performance in supercapacitors.
