Abstract
Abstract The adsorption of in MOF‐808, NU‐1000 and a series of rare‐earth CU‐10 analogues has been studied with first principles DFT and classical Monte‐Carlo methods. DFT calculations describe the interaction of with the different metal‐organic frameworks (MOFs) as physisorption, but where we can distinguish several adsorption sites in the vicinity of the metal nodes. Beyond the identification of adsorption sites, the MOFs were synthesized, activated, and characterized to evaluate their experimental and adsorption capacity. Classical Grand Canonical Monte‐Carlo (GCMC) simulations for the adsorption of are in very good agreement with DFT results for identifying the most favored adsorption sites in the MOFs. In contrast, a rather mixed agreement between GCMC simulations and experimental results is found for the estimation of adsorption capacity of several MOFs studied toward and .
