Abstract:
A quaternary phosphonium salt polymer loaded bimetallic monatomic catalyst, and a preparation method and a use. The quaternary phosphonium salt polymer loaded bimetallic monatomic catalyst comprises a first metallic active component, a second metallic active component, and a quaternary phosphonium salt polymer carrier; the first metallic active component and the second metallic active component are loaded on the quaternary phosphonium salt polymer carrier; the first metallic active component is a mononuclear complex of a first metal; the second metallic active component is a mononuclear complex of a second metal; the quaternary phosphonium salt polymer carrier is obtained by means of a quaternary phosphonium salt polymer; the quaternary phosphonium salt polymer is obtained by means of the polymerization reaction of a quaternary phosphonium salt containing a carbon-carbon double bond; the first metal is at least one selected from Rh, Ir, and Au; and the second metal is at least one selected from Ni, La, Ru, Co, and Mn. The quaternary phosphonium salt polymer loaded bimetallic monatomic catalyst has very high carbonylation activity and stability.
