The invention discloses a catalyst for low-pressure olefin polymerization and a preparation method and application thereof, and belongs to the technical field of organic porous crystalline polymers and COF materials thereof. The preparation method comprises the following steps: (1) preparing an active sample TdDa: mixing 2, 4, 6-tri (4-aminophenyl)-1, 3, 5-triazine, 2, 5-dihydroxy terephthalaldehyde, mesitylene and ethanol, and reacting to obtain the active sample TdDa; (2) preparing a catalyst Zr-TtDa: putting TtDa and ZrCl4 into a reaction container, injecting tetrahydrofuran under vacuum, heating, stirring, centrifuging and drying to obtain dry Zr-TtDa. The catalyst disclosed by the invention has the beneficial effects that the catalyst is a COF-based Zr metal catalyst and is the first heterogeneous olefin polymerization catalyst constructed by introducing a molecular Zr catalyst into a COF pore channel. The synthesis method is simple, pore channels are methylated, raw materials are ...
