Phosphine-containing organic mixed polymer-metal heterogeneous catalyst, and preparation method therefor and application thereof

A hierarchical pore structure phosphine-containing organic mixed polymer-metal heterogeneous catalyst, and a preparation method therefor and an application thereof in an olefin hydroformylation reaction. The heterogeneous catalyst uses metal Rh, Co or Ir as an active component and uses the phosphine-containing organic mixed polymer of a hierarchical pore structure as a carrier, and the phosphine-containing organic mixed polymer is formed by means of copolymerization of a polydentate organic phosphine ligand and a monodentate organic phosphine ligand. The obtained catalyst has higher stability.
