## Abstract In this article, activated carbon aerogels (ACAs) were prepared by CO~2~ activation. Their pore structures were investigated by N~2~ adsorptionβdesorption analysis. ACAs have excellent microporosity (e.g. 0.36 cm^3^/g) and mesoporosity (e.g. 1.72 cm^3^/g). Adsorption characteristics of
Activated carbons prepared from two bituminous coals were used to adsorb phenol in aqueous solutions. The major diΓΎ erence between the coal precursors is the oxygen content. The carbon preparation consisted of carbonization of the coals followed by activation in to various CO 2 extents of burn-oΓΎ .
