Cation‐Exchange Porosity Tuning in Anionic Metal–Organic Frameworks for the Selective Separation of Gases and Vapors and for Catalysis

Abstract

Temperature matters! The separation efficiency of complex mixtures of gases (acetylene, carbon dioxide, methane, nitrogen) and vapors (benzene, cyclohexane) by adsorption on A[Cu3(μ3-OH)(μ3-4-carboxypyrazolato)3] (A@1) metal–organic frameworks depends on temperature and the extraframework cation A (see picture). NH4@1 also behaves as an oxidation catalyst.
