配位不饱和铁中心金属有机框架制备方法的研究进展

Methods for Preparation of Coordination Unsaturated Iron Central Metal Organic Frameworks

金属有机框架材料(MOFs)在化工废水、废气多相催化领域的应用引起了广泛关注。由于铁基MOFs中铁-氧(Fe-O)团簇的存在使其具有较多的不饱和铁位点和较高的孔隙率、化学稳定性,其作为非均相催化剂具有巨大潜力。对于铁基MOFs,增加Fe^(2+)配位不饱和位点的数量,能显著增强其催化性能。目前,高Fe^(2+)含量的Fe-MOFs的合成及应用仍存在很大的发展挑战。本文归纳了几种配合不饱和铁中心金属有机框架的制备方法,旨在进一步加快Fe^(2+)配位不饱和位点铁基MOFs的研究及应用。

The application of metal-organic frameworks in the field of heterogeneous catalysis of chemical wastewater and waste gas has attracted wide attention.Due to the presence of Fe-O clusters in Fe-MOFs,they have more unsaturated iron sites,higher porosity and chemical stability,so they have great potential as heterogeneous catalysts.For Fe-MOFs,increasing the number of Fe^(2+)coordination unsaturated sites can significantly enhance their catalytic performance.At present,the synthesis and application of Fe-MOFs with high Fe^(2+)content still face great challenges.In this paper,several methods for the preparation of metal-organic frameworks with unsaturated iron centers are summarized in order to further accelerate the research and application of Fe-MOFs with unsaturated Fe^(2+)coordination sites.
