摘　　要：工业化的急速发展导致大气中CO_(2)的浓度急剧增加,给人类的生活带来了严重的威胁.因此,亟需发展碳捕集、利用与封存技术用于降低CO_(2)的排放量.在多种方法中,膜分离技术逐渐成为全球碳捕集技术的主要发展方向.膜材料是膜的核心,随着新型制膜材料的不断涌现,一系列高性能气体分离膜层出不穷.离子液体(ILs)作为一种新型材料,因其在CO_(2)分离过程中具有不易挥发、结构可调、对CO_(2)有优异的亲和力等特点而备受欢迎.然而,由于ILs的高黏度和高成本限制了其在工业领域的应用.将ILs与二维纳米材料相结合,得到的新型复合膜兼具ILs和二维纳米材料的优势,可突破ILs的缺陷,成为未来膜材料的研究趋势之一.本综述以ILs为核心,重点介绍了将IL限域于二维氧化石墨烯(GO)、MXene和MoS_(2)纳米材料的研究进展,讨论了ILs的性质;总结了不同ILs与二维GO、MXene和MoS_(2)材料所构建的气体分离膜在CO_(2)捕获中的应用;讨论了ILs在气体分离领域中的优势和挑战,并提出了未来的研究和发展机会.The rapid development of industrialization has led to a sharp increase in the concentration of CO_(2)in the atmosphere,posing a serious threat to human life.Therefore,there is an urgent need to develop carbon capture,utilization and sequestration(CCS)technologies to reduce CO_(2)emissions.Among various methods,membrane separation technology has gradually become the main development direction of global carbon capture technology.Membrane materials are the core of membranes,and a series of high-performance gas separation membranes have emerged with the continuous emergence of new membrane materials.Ionic liquids(ILs),as a new type of material,are popular in the CO_(2)separation process due to their non-volatile,adjustable structure and excellent affinity for CO_(2).However,the high viscosity and high cost of ILs limit the application of ILs in industry.However,the novel composite membrane obtained by combining ILs with 2D nanomaterials combines the advantages of both ILs and 2D nanomaterials,which can break through the defects of ILs and become one of the future research trends of membrane materials.For this reason,this review focuses on the research progress of limiting ILs to 2D GO,MXene and MoS_(2)nanomaterials with ILs as the core,and discusses the properties of ILs.In addition,the application of gas separation membranes constructed by different ILs with 2D GO,MXene and MoS_(2)materials in CO_(2)capture is presented.Finally,the advantages and challenges of ILs in gas separation are discussed,and future research and development opportunities are presented.
