摘要
本文对近年来离子液体(ILs)吸收氧气(O2)及其在分离、活化O2方面的研究进展进行了系统地论述.首先,概述了常规ILs、Co(Ⅱ)螯合型ILs和ILs支撑液膜(SILMs)吸收分离O2的研究工作,并着重讨论了阴离子种类和体积大小、阳离子种类和烷基取代基碳链长度等内在因素以及温度和压力等外在因素对ILs吸收O2性能的影响.其次,比较了ILs吸收O2、二氧化碳(CO2)和氮气(N2)等气体的性能差异,并结合△solH■m和△solG■m等热力学性质对此差异进行了深入分析.最后,重点论述了ILs活化O2的机理及其在金属-O2电池和一锅氧化级联催化反应中的应用,并对ILs吸收、分离和活化O2领域的后续研究提出了展望与建议.
In this paper,the recent research progress on oxygen absorption,separation and activation by ionic liquids(ILs)has been reviewed.Firstly,the research on oxygen absorption and separation was generally summarized,including conventional ILs,Co(Ⅱ)chelated ILs,and supported ionic liquid membranes(SILMs).The performance of oxygen absorption by ILs was mainly discussed,which is influenced by temperature,pressure,the species and volume size of anions,and the species and carbon chain length of alkyl substituent of cations.Secondly,the performance difference of ILs in absorbing oxygen,carbon dioxide and nitrogen was compared,which was analyzed through thermodynamic properties such as △solH■m and △solG■m.Finally,the mechanism of oxygen activation and its applications in oxygen-metal battery and one-pot oxidative cascade catalysis were discussed,and some suggestions about following research of oxygen absorption,separation and activation were proposed.
