文摘

The Law of Corresponding States for classical gases is well established. Recent attempts at developing an analogous Law of Corresponding States for gas physisorption, however, have had limited success, in part due to the omission of relevant adsorption considerations such as the adsorbate volume and cooperative adsorbate–adsorbate interactions. In this work, we modify a prior Law of Corresponding States for gas physisorption to account for adsorbate volume, and test it with experimental data and a generalized theoretical approach. Furthermore, we account for the recently reported cooperative adsorbate–adsorbate interactions on the surface of zeolite-templated carbon (ZTC) with an Ising-type model and in doing so show that the Law of Corresponding States for gas physisorption remains valid even in the presence of atypically enhanced adsorbate–adsorbate interactions.
