| description | A non-metal catalyst for synthesizing polycarbonate by CO2 and a preparation method therefor are provided. The preparation method of the non-metal catalyst includes the following steps: dissolving a hydroxyl functionalized organic ammonium halide monomer, a quaternary phosphonium salt monomer, and a hydroxyl functionalized imidazole salt monomer in a solvent, and polymerizing the mixture under the action of an initiator to obtain the non-metal catalyst for synthesizing the polycarbonate by using CO2. The non-metal catalyst prepared by the present invention is used as a heterogeneous catalytic material, is applied to a system for preparing polycarbonate by a one-step copolymerization reaction of CO2 and an epoxy compound, has high catalytic activity, does not need an additional cocatalyst or a solvent, efficiently converts CO2 into the polycarbonate, has no impurities such as metal in the product, and has the advantages of easy separation, recycling, and the like. |
