Ordered mesoporous carbon CMK-1 was partially graphitized during carbonization treatment of furfuryl alcohol (FA) polymer inside the ordered mesopores of Ni-loaded MCM-48. FA polymer was successfully produced within the mesopores of MCM-48 by thermal treatment at 90 degrees C. A typical weight decrease of the FA-polymer/MCM-48 composite occurred from 300 to 400 degrees C by carbonization treatment. Ni(II) species acts as a catalyst for dehydrogenation from 500 to 640 degrees C, and then CH4 fragments formed in situ can reduce Ni(II) to Ni(0) at 640 degrees C. The metallic Ni thus formed can then act as a catalyst for the formation of the graphitic structure within the mesopores of MCM-48 at 1000 degrees C. The CMK-1 obtained with the aid of the Ni catalyst exhibited a higher electric double-layer capacitance with a tetraethylammonium tetrafluoroborate/propylene carbonate electrolyte, compared to normal CMK-1. The results suggest that the edge planes of the graphitic domains in CMK-1 are predominantly exposed on the surface of carbonaceous walls, which leads to an increase in the number of adsorptive sites for the electrolyte during the capacitance measurements.
