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 desulfurization 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 capacity was found 30.7 mgS/g(Y-MOFs).The Ln-MOFs materials had excellent reusability.
The rare earth metal-organic frameworks (Ln-MOFs) materials, Ln (BTC) (H2O) · were synthesized using the rare earth metal (Ln = Sm, Eu, Tb, Y) -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 desulfurization 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 capacity was found 30.7 mgS / g (Y-MOFs). The Ln-MOFs materials had excellent reusability.
