Water Adsorption and Insertion in MOF‐5
The high surface areas and tunable properties of metal−organic frameworks (MOFs) make them attractive materials for applications in catalysis and the capture, storage, and separation of gases. Nevertheless, the limited stability of some MOFs under humid conditions remains a point of concern. Understanding the atomic-scale mechanisms associated with MOF hydrolysis will aid in the design of new c...
متن کاملWater adsorption in hydrophobic MOF channels.
We report an investigation of water adsorption in the hydrophobic metal-organic framework Al(OH)(1,4-naphthalenedicarboxylate) by means of molecular simulation. We show how simple molecular models allow us to reproduce the experimental isotherm, and how grand canonical Monte Carlo simulations can help elucidate the question of the thermodynamic nature of the adsorption transition, which turns o...
متن کاملSonochemical synthesis of MOF-5.
High quality MOF-5 crystals of 5-25 mum in size were prepared for the first time using a sonochemical method in substantially reduced synthesis time (ca. 30 min) compared with conventional solvothermal synthesis (24 h).
متن کاملMicrocalorimetric insight into the analysis of the reactive adsorption of ammonia on Cu-MOF and its composite with graphite oxide†
The determination of reactive adsorption mechanisms on metal–organic frameworks remains largely unexplored and knowledge in that field would provide an important stepping stone in enhancing the performance of these materials for gas separation. In this study, the mechanisms of ammonia adsorption on HKUST-1 and its composite with graphite oxide (GO) were analyzed using microcalorimetry, and the ...
متن کاملMethyl modified MOF-5: a water stable hydrogen storage material.
Water stable methyl modified MOF-5s have been synthesized via a solvothermal route. Methyl- and 2,5-dimethyl-modified MOF-5s show the same topology and hydrogen uptake capability as that of MOF-5. The H(2) uptake capacity of MOF-5, however, drops rapidly when exposed to the ambient air, whereas the H(2) uptake capacities of the methyl modified MOF-5s remain stable for 4 days.
