Unified Internal Architecture and Surface Barriers for Molecular Diffusion of Microporous Crystalline Aluminophosphates

摘要

Microporous crystalline aluminophosphates, an important class of molecular sieves, are of great interest as adsorbents, membrane materials, and heterogeneous catalysts. They are active in, for example, alkene isomerization, catalytic cracking, alkane dehydrogenation, and hydrocarbon oxidation. To expand our understanding of transport mechanisms and diffusion in microporous crystalline aluminophosphates and connect this information to their catalytic and sorption properties, scientists have performed extensive research on large crystals as model systems.
