中文摘要：
碳化物骨架碳是近年来开发的一种具有纳米结构的新型多孔碳骨架材料。该材料以多种碳化物为前驱体，在150-1650℃用卤素、超临界水蒸气或刻蚀剂于低压或真空下将碳化物中的非碳原子移出，在原子水平调控碳化物骨架碳结构。该材料具有成本低、比表面积大、孔径分布窄且精确可调等特点。本文介绍了不同碳化物前驱体制备骨架碳的工艺及骨架碳的孔隙率、比表面积和孔径分布等性质，并讨论了碳化物骨架碳在储氢、超级电容器和摩擦磨损等领域的应用。
英文摘要：
Carbide derived carbon is a new kind of porous skeleton carbon materials with nanostructure. Carbide derived carbon is produced by selective extraction of metal atoms from a carbide crystal lattice by halogens, supereritical water, oxygen at a low partial pressure, or other etchants in vacuum and temperature at 150-1 650℃. Its nanostructure can be controlled at atom level with the advantages of low cost, high specific surface area, narrower pore-size distribution and fine-tuning of the pore structure. This paper summarizes the preparation technology and porosity, specific surface area, pore size distribution of carbide derived carbon from different carbides and introduces its application in gas-storage, supercapacitor and carbon coating in tribology.
