摘要

To clarify the nature of cation sites, such as the strength of the electric field exerted by them, their location, etc., in zeolite pores, adsorption of methane on a series of ion (Li, Na, K and Rb) exchanged zeolites (FAU, FER and MOR) with different Si/Al ratios was discussed based on IR spectroscopy and adsorption thermodynamics. The interaction energy of methane with the zeolites was strongly correlated with the micropore size of the main channel rather than the cation content in the zeolites. On the contrary, the strength of the electric field in the vicinity of Na sites increased with the increase in the Si/Al ratio of the zeolite in spite of the decrease in the amount of cations. All of the cations incorporated in the zeolites studied were not always available for methane adsorption since cations in the zeolites are distributed into deep (methane inaccessible) sites and surface (methane accessible) sites, and the amount of inaccessible sites often increased with the decrease in the size of the cation.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
