Size determination of ultramicropores and small mesopores using a calculation procedure based on the tangents of comparison plot

Abstract

Pore size distribution (PSD) curves of synthesized hollow silica spheres with ultrmicropores and small mesopores were obtained from calculations based on the BJH, KJS, SF, MP, NLDFT models and Prof. Zhu’s method. Comparisons indicate that Zhu’s method not only gives reasonable small mesopore size but also could be further extended to the ultramicropores region for the PSD evaluation.
