Progress of preparation of carbide-derived carbon and application in gas storage and supercapacitors

In this paper，binary carbides and ternary carbides were introduced as precursors to make carbide-derived carbons (CDCs). Nomenclature in Chinese of carbide-derived carbons was summarized. Preparation processes and principle of high-temperature Cl2-etching in a tube furnace were elaborated. Structure and properties of CDC were summarized，focusing on the latest researches in the fields of hydrogen/methane storage and supercapacitor electrode materials. The storage capacity of CDC was 18.5% for methane and 6.2% for hydrogen. As supercapacitor electrode material，its mass specific capacity was 120F/g and its volume specific capacity reached a very high value of 90F/cm3，which was potentially useful in microelectronic devices，such as MEMS. Finally，CDC could have better applications in more areas by controlling microstructure and improving performance.
