摘要
The rare earth metal-organic frameworks （Ln-MOFs） materials, Ln（BTC）（H2O）-（DMF）, were synthesized using the rare earth metal （Ln=Sm, Eu, Tb, Y） and 1,3,5-trirnesic acid （BTC） as a metal ion center and ligand, respectively. X-ray diffraction （XRD） and infrared spectroscopy （FT-IR） were employed to characterize the Ln-MOFs structural features. The property of adsorption desul- furization of Ln-MOFs materials was evaluated with thiophene/n-octane as model oil. The results showed that Ln-MOFs with rare earth metals Sm, Eu, Tb and Y had perfect crystalline and good adsorption desulfurization ability. Y（BTC）（H2O）-（DMF） material had a comparatively better activity for the adsorption desulfurization with desulfurization rate up to 80.7% and the sulfur adsorption ca- pacity was found 30.7 mgS/g（Y-MOFs）. The Ln-MOFs materials had excellent reusability.
