Selective adsorption of CO₂ in TAMOF-1 for the separation of CO₂/CH₄ gas mixtures.

ABSTRACT: TAMOF-1 is a robust, highly porous metal-organic framework built from Cu²⁺ centers linked by a L-histidine derivative. Thanks to its high porosity and homochirality, TAMOF-1 has shown interesting molecular recognition properties, being able to resolve racemic mixtures of small organic molecules in gas and liquid phases. Now, we have discovered that TAMOF-1 also offers a competitive performance as solid adsorbent for CO₂ physisorption, offering promising CO₂ adsorption capacity ( > 3.8 mmol g^-1) and CO₂/CH₄ Ideal Adsorbed Solution Theory (IAST) selectivity ( > 40) at ambient conditions. Moreover, the material exhibits favorable adsorption kinetics under dynamic conditions, demonstrating good stability in high-humidity environ
