摘 要:烯烃氢甲酰化反应是在均相或非均相催化剂的作用下实现烯烃的高值化利用。非均相催化剂具有易于分离、回收的优势,但设计同时具有高活性、高区域选择性、高稳定性面临挑战。因此开发高效的氢甲酰化多相催化剂具有重要的理论和实践意义。单原子催化剂(SAC)作为均相与非均相催化的桥梁,融合了均相催化剂活性中心原子微观环境可调的特性和固相催化剂的技术优势,可通过调控中心原子的微观环境提高氢甲酰化反应效率。以载体、含膦配体改性和异质原子辅助3个方面为着眼点,综述了单原子催化剂微观结构对烯烃氢甲酰化反应的活性、区域选择性和稳定性的调控策略,最后总结目前SAC工业化应用面临的机遇与挑战,并对其发展方向进行展望。Hydroformylation of olefin is a high value utilization of olefin in the presence of homogeneous or heterogeneous catalysts.Heterogeneous catalysts have the advantages of easy separation and recovery,but at the same time,the design of high activity,high regional selectivity and high stability faces challenges.Therefore,the development of highly efficient hydroformylation heterogeneous catalysts has important theoretical and practical significance.As a bridge between homogeneous and heterogeneous catalysis,single-atom catalyst(SAC)combines the adjustable microenvironment of the active center atoms of homogeneous catalyst with the technical advantages of solid phase catalyst,which can improve the efficiency of hydroformylation reaction by adjusting the microenvironment of the central atoms.Based on three aspects of carrier,phosphate-containing ligand modification and heteroatomic assistance,the regulation strategies of single-atom catalyst microstructure on the activity,regional selectivity and stability of hydroformylation of olefin were reviewed.Finally,the opportunities and challenges facing the industrial application of SAC were summarized,and its development direction was prospected.
