摘要：

The applicability of Kruk-Jaroniec-Sayari (KJS) pore size analysis method developed for siliceous materials with cylindrical mesopores is discussed for novel channel-like mesoporous carbons obtained by soft-templating synthesis. It was shown that a simple replacement of the statistical film thickness curves (t-curves) for argon;and nitrogen on the silica surface by the corresponding t-curves on the carbon surface makes this method applicable for pore size analysis of carbons with cylindrical mesopores. A simple way to obtain t-curves for argon and nitrogen adsorption on a nongraphitized carbon surface is discussed. (C) 2007 Elsevier Inc. All rights reserved.
