Abstract:
1. A method of preparing mesoporous carbon for a fuel cell, the mesoporous carbon containing at least one heteroatom, the method comprising: impregnating an ordered mesoporous silica (OMS) with a carbon precursor mixture comprising a carbon precursor, a compound containing the at least one heteroatom selected from the group consisting of boron and phosphorus, an acid and a solvent, wherein the compound containing the at least one heteroatom is provided in an amount such that the amount of the heteroatom in the mesoporous carbon is 0.5 to 20 parts by weight based on 100 parts by weight of the mesoporous carbon; heat-treating the impregnated OMS; carbonizing the heat-treated OMS to form an OMS-carbon complex; and removing the OMS from the OMS-carbon complex to obtain the mesoporous carbon containing the at least one heteroatom.
