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-trimesic 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.
