The present invention discloses an ordered macroporous metal-organic frameworks (MOFs) single crystal and a preparation method therefor. The method adopts a three-dimensional structure accumulated by polymer microspheres as a template and comprises: first depositing precursors of MOFs, i.e., dimethylimidazole and zinc nitrate, inside the three-dimensional template, then immersing the three-dimensional template containing the precursors in a mixed solution of aqueous ammonia and methanol, performing crystallization and then taking out the three-dimensional template, performing immersion in an organic solvent to remove the polymer three-dimensional template, and performing centrifugation to obtain the ordered macroporous MOFs single crystal. The ordered macroporous MOFs single crystal has the basic framework of zeolitic imidazolate framework-8; however, the structure of the ordered macroporous MOFs single crystal contains highly-structured ordered macropores. The diameter of the macropores can be controlled between 50 nm and 2000 nm according to the size of the used template. The method of the present invention is simple and safe; the obtained product is high in purity, complete in structure, and high in mechanical strength, and thus is suitable for use as an adsorbing material or a catalyst for a catalytic reaction.
