Abstract
MOST speculations about the detailed pore structure of carbons have been unsupported by direct experimental evidence. The classification in terms of micropores, transitional pores and macropores was developed mainly by Dubinin et al.1 on the basis of adsorption and mercury penetration investigations. These methods, however, give no information about the detailed pore geometry and only limited information about the statistical character of the structure. Molecular sieve investigations2 have led other workers to the conclusion that the pores are often slot-like. Wolff3 and Mizushima4 have proposed more specific models in which active carbons are pictured as aggregates of graphite-like plates which impose a slot-like character on the spaces between them.
