The invention relates to a metal-organic framework material UiO-66 as well as an ultrasonic synthesis method and application thereof. According to the metal-organic framework material UiO-66, Zr < 4 + >, Al < 3 + >, Fe < 3 + >, Cr < 3 + > or Zn < 2 + > are used as metal ions, terephthalic acid is used as a rigid organic ligand, the metal ions and the rigid organic ligand form a microporous material through coordinate bonds, the boundary dimension is 20-200 nm, and the metal-organic framework material UiO-66 has a cubic regular geometric appearance and can be used for preparing the metal-organic framework material UiO-66. According to the preparation method, metal ions and rigid organic ligands are dissolved in a solvent in proportion, the metal-organic framework material UiO-66 is synthesized under the ultrasonic action at a certain temperature, the ultrasonic output power is 100 W, the ultrasonic time is 30-150 min, the reaction time is short, the yield is high, and the product size is controllable.
