Owing to the high prices and other shortcomings associated with the existing methods of complex catalyst preparation, we used the UIO-66(Zr) metal-organic frameworks to directly catalyze the oxidative desulfurization (ODS) reaction. The synthesized UIO-66(Zr) was characterized using nitrogen adsorption-desorption isotherm analysis, X-ray diffraction, Fourier transform infrared spectroscopy, transmission electron microscopy, and X-ray photoelectron spectroscopy. Under optimal reaction conditions, the ODS conversion of dibenzothiophene (DBT) reached 100%. This excellent catalytic activity was attributed to the unsaturated coordination of Zr, which may produce beneficial Lewis acid sites.
