Physical adsorption of gases is the most employed technique for the characterization of porous solids. N{sub 2} adsorption at 77 K is the more used and, usually, has a special status of recommended adsorptive. The advantage of N{sub 2} adsorption is that it covers relative pressures from 10{sup -8} to 1, what results in adsorption in the whole range of porosity. The main disadvantage of N{sub 2} adsorption at 77 K is that when used for the characterization of microporous solids, diffusional problems of the molecules inside the narrow porosity (size < 0.7 nm) occur. This paper describes studies concerned with adsorption of carbon dioxide by microporous carbon materials.
