Mesoporous carbon materials are desirable electrode materials and are also useful for the separation of bulky organics. In this article, the templated synthesis of a new high surface area mesoporous carbon using hexagonal mesoporous silica (HMS) aluminosilicate is reported. Preliminary results on the electrochemical double-layer capacitance performance of the material are presented that indicate that it is superior to the commercially available carbon MSC-25. In addition, the pore structure of HMS is indirectly elucidated.
