摘要

提出了一种用离子液体控制填充金属有机骨架(MOFs)孔隙的方法，该方法可用于金属有机骨架的选择性气体吸附。以MOF ZIF-8和IL [BMIm]+[BF4]−为例，在氮氧化物自旋探针电子顺磁共振(EPR)监测下，制备了不同IL含量的复合材料。用反相气相色谱法研究了IL对这些复合材料中氮氧化物吸附的影响。

Composite Materials Based on MOF ZIF-8 and Ionic Liquid [BMIm]+[BF4]−: An EPR Study Using Nitroxide Spin Probes

A method for the controlled filling of pores in metal–organic frameworks (MOFs) with ionic liquids (ILs) has been proposed, which can be applied for selective gas sorption in MOFs. Using an example of MOF ZIF-8 and IL [BMIm]⁺[BF₄]⁻, composites with different IL content have been prepared with monitoring by electron paramagnetic resonance (EPR) of nitroxide spin probes. The effect of IL on the sorption of nitrogen(II) oxide into these composites has been studied using inversion gas chromatography.
