The syntheses methods, structure characteristics and various applications of UiO series of metal-organic frameworks (MOFs) including UIO-66, UIO-67 and UIO-68 were reviewed. The syntheses methods of UiO series of MOFs like evaporation, solvothermal method, microwave-assisted synthesis, mechanochemical synthesis, continuous flow method, and electrochemical synthesis were introduced. The detailed reaction conditions, the compositions and structures characteristic of the final products, and the advantages/disadvantages of above-stated syntheses methods were analyzed. UiO-MOFs possessed both ultrahigh thermal stability and chemical stability resulted from their strong Zr-O bond and high coordination number of Zr(IV). Considering UiO-MOFs exceptional porosity with uniform but tunable pore sizes, incredibly high internal surface areas and the active Zr-O clusters, they had been used extensively in many research fields like catalysis, photocatalysis, gas adsorption, gas separation, adsorptive removal of organic pollutants in wastewater, medical, capacitor and so on. Finally, the research trends of UiO-MOFs are prospected.
