ABSTRACT
Mesoporous carbon nanomaterials (MCNs) which possess pore sizes between 2 and 50 nm received tremendous research efforts. In comparison with mesoporous silica and metal oxide, ordered MCNs possess more fascinating physical and chemical properties, including hydrophobicity of their surfaces, high surface area, enhanced electrical and thermal conductivity, chemical stability, reduced density, and low cost of manufacture. The common approach to ordered MCNs is based on the hard-template strategy, which normally utilizes mesoporous silica as the template. Owing to the huge number of publications on MCNs reported, the synthesis strategies of hard and soft templates have been proved to be the most successful methods to prepare the MCNs with well-controlled mesostructures. The commercially available supercapacitors are mainly electrochemical double-layer capacitors, which store energy through the adsorption of both anions and cations at the interface between electrode and electrolyte.
