摘要：

Measurements of low-temperature nitrogen adsorption isotherms are used to study the energetic heterogeneity and microporosity of cellulose- and poly(acrylonitrile)-based activated carbon fibers. The energetic heterogeneities of these materials are characterized by adsorption potential distribution functions which are the composite of two overlapping peaks that arise from the adsorbents biporous microstructures. A two-term Dubinin-Radushkevich equation is used to model the micropore-filling mechanism in the materials.
