多孔液体及其二氧化碳气体分离研究进展
Review on porous liquids and its application in carbon dioxide sequestration
摘要
Abstract
As one of new porous materials,porous liquids combine the advantages of the microporous solids and liquids with permanent microporosity and fluidity,which have drawn great attention and shown great value in theoretical research and application. In this paper,the concept of porous liquids was introduced,the preparing methods of three type porous liquids were summarized,and their characteristics and synthetic conditions were analyzed. Type Ⅰ porous liquids were neat liquids consisting of rigid hosts with cavities,obtained by properly modifying large organic molecules or nanoparticles to maintain liquid phases at room temperature. Type Ⅱ consisted of rigid molecules with cavities dissolved in solvents which are sterically prevented from entering the host cavity. The novel fabricated method was preparation of cavity hosts by one-pot synthesis to match solvent molecules well. Type Ⅲ also consisted of steric solvents and cavity hosts. The key to Type Ⅲ was keeping fluid porous phases steadyvia matching microporous framework materials with steric solvents or dispersing agents well. In addition,the latest research progresses and status on CO2 sequestration with porous liquids were reviewed. Advantages,disadvantages and mechanisms of capturing CO2 using different types of porous liquids were analyzed. Finally,the outlook of synthetic methods and applications in gas separation based on porous liquids was presented.关键词
