Solvothermal synthesis of TiO₂@MIL-101(Cr) for efficient photocatalytic fuel denitrification

Solvothermal synthesis technique is an effective method to create composite materials. In this paper, a series of TiO₂@MIL-101(Cr) were prepared by the solvothermal method for photocatalytic denitrification of pyridine in fuel under visible light irradiation. The products were characterized by XRD, FT-IR, SEM, TEM, BET, DRS and ESR. The result shows that 20%TiO₂@MIL-101(Cr) has high catalytic activity, the pyridine removal efficiency reaches values as high as 70% after irradiation for 240 min. Finally, we obtained the possible mechanism of photocatalytic denitrification according to the HPLC-MS spectrometry results analysis.
