摘要: A zeolite-like microporous tetrazole-based metal–organic framework (MOF) with 24 nuclear zinc cages was synthesized and characterized. It exhibits high CO2 adsorption capacity up to 35.6 wt % (8.09 mmol/g) excellent CO2/CH4 selectivity at 273 K/1 bar, being among the highest values known date. Theoretical calculations based on simulated annealing techniques periodic DFT revealed that is predominantly located around inner surface of through multipoint interactions, in particular, aromatic tetrazole rings. Importantly, it first time interactions between molecules frameworks resulting uptake are observed.
