金属有机框架吸附存储与分离CH_4、CO_2研究进展

Research progress of metal-organic frameworks for CH_4 and CO_2 adsorption and separation

煤炭在全球能源中占有相当大的比例,并将长期是世界主要的一次性能源之一。煤炭开采过程中产生的瓦斯气体和燃烧过程中产生的CO_2气体,不仅对人身安全构成威胁也对环境造成极大的破坏,违背了可持续发展战略的理念,因此煤炭的高效清洁利用成为目前亟需解决的问题。金属有机框架是近年来发展起来的一类具有一定孔径尺寸和表面积的有机-无机杂化材料,由于结构的特殊性,决定了其在气体吸附存储与分离方面有着巨大的应用潜力。从金属有机框架的结构特点出发,综述了近年来其在甲烷、CO_2吸附分离方面的研究进展。

Coal occupies a considerable proportion in global energy and will be one of the world＇s most important primary energy for a long time.However,the hazardous and pollutant gas generated in the process of coal mining and usage not only posed a threat to personal safety but also been contrary to the will of sustainable development strategy.As a result,the efficient use of coal has become an important and urgent problem to be solved.（MOFs）is a newly developed organic-inorganic hybrid material with certain pore size and surface area.The special structure of MOFs is decisive to its great application potential in gas separation and storage.Based on the structural charateristics of MOFs,the progress of MOFs in the adsorption and separation for CH4,CO2 was reviewed.
