氨基改性介孔分子筛吸附CO_(2)的研究进展

Research Progress of Mesoporous Molecular Sieves Functionalized by Amino Group

人为CO_(2)排放量持续增加导致温室效应愈演愈烈的情况仍为当今面临的最为急迫的问题之一。氨基改性介孔分子筛因具有CO_(2)吸附量高、吸附速率快等优点,成为近年来研究热点。本文综述了用胺对一系列常见的介孔分子筛进行改性的研究进展,以及它们的CO_(2)吸附性能。还分别讨论了物理浸渍、化学嫁接和双功能化对分子筛改性的优缺点。综合分析后对氨基改性介孔分子筛研究方向提出展望。

The growing greenhouse effect due to the continuous increase in anthropogenic CO_(2) emissions remains one of the most pressing issues today.Amine-modified mesoporous molecular sieves have become a research hotspot in recent years because of their high CO_(2) adsorption performance and fast adsorption rate.The progress of research on the modification of a series of common mesoporous molecular sieves with amines and their CO_(2) adsorption properties are reviewed.The advantages and disadvantages of amine modification of molecular sieves by physical impregnation,chemical grafting and bifunctionalization are also discussed separately.The comprehensive analysis is followed by an outlook on the research direction of amino-modified mesoporous molecular sieves.
