Physical adsorption and the porosity of carbons, with special reference to the structure of micropores

The problem of porosity in carbonaceous materials is briefly reviewed. Microporosity is investigated from the point of view of physical adsorption from the gas phase on graphite-like surfaces. Theoretical considerations show that the micropores can be treated as slots between the graphitic planes of the microcrystallites. The minima of the adsorption potentials are derived from the limiting heats of adsorption, measured by GSC.
