Progress in the performance regulating strategies of single-atom catalysts for hydroformylation olefin reaction
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 effi-ciency 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 hydro-formylation of olefin were reviewed.Finally,the opportunities and challenges facing the industrial applica-tion of SAC were summarized,and its development direction was prospected.
