  • Method of making the porous carbon material of different pore sizes and porous carbon materials produced by the method
    Patent number: 7803345
    Abstract: A method for making the microporous carbon with modified pore size distribution and advanced sorption behavior. The carbon is derived from metal or metalloid carbides. The method employs the use of oxidant in reaction medium that during the carbide conversion into carbon widens small micropores, which otherwise would be hardly accessed by sorbing molecules or ions in practical applications. The microporous carbon obtained is free of impurities and possesses extremely narrow pore size distribution.
