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.
Claims17
A method of producing porous carbon, comprising depositing carbon in the pores of a porous inorganic template material having a surface area of at least 1 m.sup.2 g-1 and thereafter removing the template material to leave a porous carbon product having a geometry corresponding to that of the template material.
