金属有机骨架用于CO_(2)的吸附和转化

Adsorption and transformation of CO_(2)by metal organic framework

近年来,大气中CO_(2)的迅速增加威胁着人类社会和自然环境。通过催化剂将CO_(2)转化为高附加值化学品的碳转化技术是解决该问题的有效途径。金属有机骨架(metal-organic framework,MOF)是一种比表面积大,孔结构高度有序,拓扑类型多样,稳定性好的材料。MOF材料的特性使其具有广阔的应用前景,包括气体吸附、存储与分离,传感,药物传递,荧光和催化等。综述MOF用于CO_(2)吸附与转化的结构优势,包括柔性的骨架、路易斯活性位点、可调的孔径以及缺陷结构等。

In recent years,the rapid increase emission of CO_(2)into the atmosphere threatens human society and natural environment.In order to solve this problem,researchers put forward the carbon conversion technology to convert CO_(2)into high value-added chemicals through catalysts.Metal-organic framework(MOF)is a kind of material with large specific surface area,highly ordered pore structure,diverse topology type and good stability.These properties of MOF make it have wide application prospects,including gas adsorption,storage and separation,sensing,drug delivery,fluorescence and catalysis.In this paper,MOF as a catalyst for CO_(2)adsorption and conversion is reviewed,including flexible framework,Lewis active sites,controllable pore size and defect structure.
