摘　　要：解决工业过程污染气体的过量排放问题,具有重要的科学和环境意义。离子液体(ILs)作为室温呈液态的绿色溶剂,在气体捕集转化方面具有独特的优势,但天然的高黏度特性严重阻碍了其工业应用。本团队基于多年研究发现,不执拗于大幅降低离子液体的黏度,而顺其自然,通过“微颗粒化”技术,实现离子液体于准静止状态的高效利用,是离子液体适应工业化的有效路径之一。鉴于此,综述了以二氧化硅(SiO_(2))为介质的离子液体微颗粒,及其衍生的离子液体纳-微界面反应单元在气体捕集(VOCs和CO_(2))和CO_(2)转化方面的应用研究进展,探讨了微颗粒化离子液体体系较传统体系的特性优势,并分析了离子液体“微颗粒化”的应用前景及工业可行性。It is of great scientific and environmental significance to solve the problem of excessive discharge of polluting gases in industrial processes.Ionic liquids(ILs),being green solvents in a liquid state at room temperature,possess unique advantages in gas capture and conversion.However,their inherent high viscosity poses a major challenge for industrial applications.Based on years of research,our team has discovered that instead of significantly reducing the viscosity of ILs,an effective approach to adapt them for industrial use is through the utilization of“micro particulation”technology,enabling efficient deployment of ionic liquids in a quasi-stationary state.In view of this,the research progress on the application of ionic liquid micro particles with silica as a medium and its derived ILs nano-micro interface reaction units for gas capture and conversion is reviewed,the characteristic advantages of micro particulated IL systems over conventional systems are discussed,and the“micro particulation”of ILs is analyzed.The application prospects and industrial feasibility of“micro particulation”of ILs are discussed.
