摘要
综述了新型绿色溶剂离子液体在CO2固定和转化利用领域的应用研究进展.根据离子液体的结构特征和CO2的固定机理,离子液体固定CO2可以分为常规离子液体固定、功能化离子液体固定和离子液体固定转化.常规离子液体固定CO2为物理作用过程,功能化离子液体固定CO2为化学作用过程,而离子液体固定转化CO2的过程在固定CO2的同时又实现了CO2从工业废气直接到有用化学品的转变.因此,设计合成高效的功能化离子液体来实现CO2的固定转化一体化将具有重要的意义。
Research progress in application of CO2 fixation and transformation using ionic liquids (ILs) has been systematically discussed. There are three kinds of CO2 fixation using ILs according to structures of ionic liquids and mechanism of fixation, which are CO2 fixation using common ILs, CO2 fixation using task-specific ILs and fixation-conversion of CO2 using ILs. The mechanism of CO2 fixation using common ionic liquids is physical absorption and that of task-specific ILs is chemical process, while fixation and conversion of CO2 using ILs will be a good way from flue gas to new chemicals. Design and synthesis of high effective task-specific ILs to achieve the goal of fixation and conversion of CO2 will be a key step applied in CO2 fixation.
