英文摘要	the amine-decorated microporous metal-organic framework cau-1 was readily synthesized and activated using a home-made efficient protocol. it exhibited a high heat of adsorption for co2, high co2 uptake capacity, and an impressive selectivity for co2 over n-2. at 273 k and up to 1 atm, co2 uptake capacity can reach as much as 7.2 mmol g(-1). comparatively, the ch4 and n-2 uptakes at 273 k and 1 atm were only 1.34 mmol g(-1) and 0.37 mmol g(-1), respectively. the co2/n-2 selectivity was 101 : 1 at 273 k. the isosteric heat of adsorption (q(st)) for co2 was similar to 48 kj mol(-1) at the onset of adsorption, and it decreases to similar to 28 kj mol(-1) at higher co2 pressures. furthermore, cau-1 can adsorb 2.0 wt% and 4.0 wt% hydrogen at 77 k under 1 atm and 30 atm, respectively. the adsorption characteristics of cau-1 for methanol investigated in situ with a quartz crystal microbalance (qcm), indicated that this particular mof structure can be used as a highly sensitive sensor for methanol detection such as direct methanol fuel cells.
