Mesoporous carbons synthesized by soft-templating method: Determination of pore size distribution from argon and nitrogen adsorption isotherms

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.
