摘　　要：简单介绍了金属有机骨架(MOFs)的制备及其特点。详细综述了单金属MOFs和双金属MOFs在选择性催化还原(SCR)脱硝领域的研究进展,其中重点介绍了MOFs脱硝催化剂的制备方法和不同形貌的MOFs对其脱硝性能的影响,MOFs脱硝催化剂脱硝反应机理等内容,在此基础上提出了“在单金属MOFs基础上引入其他活性组分,减小MOFs的颗粒粒径,可以增加比表面积和活性位点数量;将MOFs隔绝空气高温下煅烧可以使有机配体碳化,暴露出更多的活性位点,可以提高催化活性”的结论。最后展望了MOFs脱硝催化剂未来的发展方向。The characteristics of metal-organic frameworks(MOFs)are briefly introduced.The research progress of monometallic MOFs and bimetallic MOFs in the field of denitrification was reviewed in detail,in which the preparation method of MOFs denitrification catalyst,the properties of organic ligand and the influence of MOFs with different morphologies on their denitrification performance.Therefore,this paper proposed that"introducing other active components on the basis of mono-metal MOFs and reducing the particle size of MOFs can increase the specific surface area and the number of active sites."The calcination of MOFs under air isolation can carbonize the organic ligands,expose more active sites,and improve the catalytic activity".Finally,the future development direction of MOFs denitrification catalyst is prospected.
