Physical Sorption Characterization of Nanoporous Materials

摘要

Nanoporous materials have become more important in various application fields. For the pore characterization, gas physical sorption analysis is a popular and powerful tool for materials with pore diameters ranging from 0.5 to 100 nm. In this article, the principle of sorption analysis and the sorption measurement have been shown. In addition, several analytical methods frequently used for the calculation of surface area, pore diameter and microporosity have also been introduced.
