Mesoporous carbon nan materials is a carbon-based new materials with nan meter scale at least one dimension in the three-dimensional space and with high specific surface and ordered cavities whose pore diameter is about 2-50nm , which has drawn great attention since its discovery. Those merits above make mesoporous carbon nan materials a potential application in the biology, energy, environment and other aspects. Many researchers have reported about the preparation of mesoporous carbon nan materials with diverse materials as well as various methods, such as nanocasting method and template method.
