功能化金属有机框架材料催化二氧化碳转化研究进展

作为主要温室气体,二氧化碳(CO_2)导致了全球变暖与海洋酸化,同时CO_2也是重要的C1资源。在温和条件下,利用催化剂将CO_2高效、高选择性地转化为具有高附加值的化学品,对缓解CO_2给气候变化带来的负面影响和减少对化石能源的依赖具有重要意义。作为一类新兴的多孔晶态材料,金属-有机框架(metal-organic frameworks,MOFs)同时具备多相催化剂的可分离回收再利用以及均相催化剂的高选择性和高活性等性质,是优良的多相催化剂。本文主要聚焦功能化MOFs催化剂的结构特性及其在催化转化CO_2方面的应用,着重介绍该领域近期的研究进展,并对今后该领域的研究趋势及应用前景进行了展望。

Progress in Functional Metal-Organic Frameworks for Catalytic Conversion of Carbon Dioxide

Carbon dioxide (CO₂), as a major greenhouse gas, causes global warming and ocean acidification, and is also an important C1 resource at the same time. It is of great significance for high efficiently and selectively conversion of CO₂ into high value-added chemicals using desired catalysts under mild conditions to mitigate the negative impact of CO₂ on climate change and reduce the dependence on fossil energy. Metal-organic frameworks (MOFs), as a new kind of porous crystalline materials, are attractive heterogeneous catalysts due to their reusability of heterogenous as well as high selectivity and acitivity of homogenous catalysts. This review mainly focuses on the up-to-date developments of functional MOFs catalysts with emphasis on their architecture characteristics and applications in catalytic conversion of CO₂. Recent research progress together with the prospect and outlook of MOFs in this field will be introduced.
