  • Preparation of porous carbon
    Patent number: 4263268
    Abstract: Porous carbon, suitable for instance for chromatography and as a catalyst support is formed by depositing carbon into the pores of a porous inorganic template such as silica gel, porous glass or a porous oxide, e.g. alumina, and thereafter removing the template as by dissolution or evaporation. Carbon is preferably deposited as a polymerizable organic material that is polymerized in situ in the template pores and then pyrolyzed to carbon.
