The invention relates to a high-performance catalyst for preparing diol by hydrating epoxyalkane, a preparation method and application of the catalyst. The catalyst is a polymer catalyst, and the polymer is prepared by polymerizing diamine with at least one monomer selected from 1,3,5-tri(3-formyl-4-hydroxyphenyl)benzene or substituted 1,3,5-tri(3-formyl-4-hydroxyphenyl)benzene and then conducting reacting with a metal salt. The catalyst has high activity and stability for preparing the diol by hydrating the epoxyalkane under high and low water ratios, and has excellent recyclability without activation, so that the problems of high required water ratio and poor stability of the catalyst for preparing the diol by hydrating the epoxyalkane in the prior art are solved.
