摘要: The intrinsic chemical properties of carbon can be modified by the heteroatom funcationalization of graphene geometries such as at the edges, defects or strained regions. Heteroatom (such as O, N, B, P, S) modification has been proven to be an effective way to tune the chemical and electrical properties of the carbon surface for catalysis and electrochemical process. Successful catalysis and electrochemical application of heteroatom modified carbon requires the manipulation of heteroatom-containing functional groups on a suitably prepared mesoscopic material allowing for efficient transport of reactants and electrons. The surface of carbon materials is usually terminated by a variety of functional groups. Sulphur containing functional groups allow to mediate carbon chemistry in different ways depending on their oxidation states. Sulphur containing carbon was described for biomass conversion, heavy metal recovery and supercapacitor. We explored the idea of aliphatic/aromatic sulphur mediated mesoporous carbon (MC) for use in supercapacitors. The reason for selecting OMC was attributed to their large surface area, as well as to their uniform and tunable pore sizes. Furthermore, chemically derived OMC are intrinsically decorated by abundant defect sites, such as functional groups, distortions and rough surfaces deviated from planer graphene on the lateral surface and edges. Here sites allow for frequent surface modifications by sulphur groups that may reversibly provide active species for supercapacitor applications.
