Abstract: A new type of mesoporous carbon (denoted as C-MTS-9) was synthesized with mesoporous titanosilicate MTS-9 as template. The template MTS-9 prepared from zeolite “seed solution” has some common structural characters including the thicker wall, the higher hydrothermal stability, disorder in some extent, zeolitelike connectivities in the wall. The mesoporous carbon sieve C-MTS-9 was investigated by XRD, TG, TEM, and N₂ adsorption/desorption techniques. The characteristic results show that the mesoporous carbon sieve C-MTS-9 has larger BET surface areas than conventional CMK-3. In addition, the mesoporous carbon sieveC-MTS-9 exhibits narrower pore size distribution. In particular, the mesoporous carbon sieve C-MTS-9 shows interesting electrochemical doublelayer capacitance (EDLC) behavior resulted from regular 3D interconnected mesopores.
