Abstract
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.
期刊介绍:
Doklady Physical Chemistry is a monthly journal containing English translations of current Russian research in physical chemistry from the Physical Chemistry sections of the Doklady Akademii Nauk (Proceedings of the Russian Academy of Sciences). The journal publishes the most significant new research in physical chemistry being done in Russia, thus ensuring its scientific priority. Doklady Physical Chemistry presents short preliminary accounts of the application of the state-of-the-art physical chemistry ideas and methods to the study of organic and inorganic compounds and macromolecules; polymeric, inorganic and composite materials as well as corresponding processes. The journal is intended for scientists in all fields of chemistry and in interdisciplinary sciences.
