摘要: Polyacrylonitrile (PAN)-based activated carbon fibers (ACFs) prepared by various activation methods were characterized using low-temperature nitrogen adsorption over a wide relative pressure from 10(-6) to 1. Nitrogen is standard tool for determination of porous structure parameters. In the present work, we carried out extensive studies series PAN-ACFs different methods. It was shown that high-resolution alpha(S) plot provided valuable information about structural properties samples under study. The pore size distributions study calculated employing regularization method according density functional theory. By these analyses, development and dominant pores can be clearly observed. Moreover, measurement could provide profound insight into heterogeneity ACFs. Copyright 2000 Academic Press.
