| 中文摘要: |
| 炔烃的半氢化反应在有机合成和精细化工领域具有重要地位,如何同时兼顾反应活性和选择性仍存在很大挑战。目前已有多种材料被应用于相关催化,其中,金属-有机框架(MOFs)及其复合材料受到越来越多关注。MOFs的多孔性、结构可修饰性、空间限域效应、协同催化等优点,使其在炔烃的半氢化反应中表现出独特的应用前景。本文综述了MOFs在炔烃的半氢化反应生成烯烃过程中的应用,主要根据活性催化位点的类别展开介绍,重点阐述了不同体系中催化效果和结构之间的关系。 |
| 英文摘要: |
| The semihydrogenation of alkynes into alkenes is of great importance in organic synthesis and fine chemical industry. Unfortunately, it is still challenging to simultaneously achieve high conversion with excellent selectivity. A variety of catalysts have been used in the semihydrogenation of alkynes, among which metal-organic frameworks (MOFs) and their composites have attracted more and more attention. MOFs have shown prominent performance as heterogeneous catalysts in the semihydrogenation of alkynes due to their advantages in porosity, structural modification, confinement effect, and cooperative catalysis. Herein, the application of MOFs in the selective semihydrogenation of alkynes into olefins are reviewed. Catalytic systems with different types of active sites are discussed, with emphasis on the structure-function relationship between the MOF catalyst structure and the catalytic performances. |
