Abstract

Adsorbate-adsorbate interactions are analyzed in the framework of the Ono-Kondo model. The results show that, at large amounts of adsorption, intermolecular interactions in the adsorbed phase are repulsive. In the range of small adsorption, microporous systems also can show repulsions due to limitations of the adsorption space. This effect also is possible in macroporous adsorbents with active site spacing that is less than that of the adsorbate bulk liquid. Copyright 2000 Academic Press.

摘要

在小野-近藤模型的框架内分析吸附质-吸附质相互作用。结果表明,在大量吸附时,吸附相中的分子间相互作用是排斥性的。在小吸附量范围内,由于吸附空间的限制,微孔系统也可能表现出排斥作用。在活性位点间距小于吸附质本体液体的大孔吸附剂中,这种效应也是可能的。版权所有2000年学术出版社。
