## 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
Nitrogen adsorption isotherms on activated carbon fibers (ACFs) were measured at 77.3 K in the relative pressure range from 10(-7) to 0.995. The low relative pressure data are examined in detail in order to characterize the microporosity and the surface heterogeneity of the samples studied. The pore
