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.​
