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 structure of ACFs was studied by using the alphas plot and DFT methods. Adsorption potential and adsorption energy distributions were also calculated. The results showed that ACFs are highly microporous and in some cases contain small mesopores (2-4 nm). ACFs exhibit a significant structural and energetic heterogeneity.

在77.3 K下，测量了活性碳纤维（ACF）在相对压力范围为10^(-7)至0.995之间的氮气吸附等温线。详细研究了低相对压力数据，以表征所研究样品的微孔率和表面非均质性。采用α图和密度泛函理论（DFT）方法研究了ACF的孔结构。还计算了吸附势和吸附能分布。结果表明，ACF具有高度微孔性，在某些情况下还含有小的中孔（2-4纳米）。ACF表现出显著的结构和能量非均质性。版权所有1998年学术出版社。
