Facile Fabrication of PTA@MOF-808H Nanocomposites in Acidic Media Employing Hydrogen Peroxide for Catalytic Oxidative Desulfurization of Fuel Oil

This research paper describes the fabrication of a series of PTA@MOF-808(Zr)H composite synthesized by the impregnation method. The structural and microstructural properties of the nanocomposites were investigated by using Fourier transform infrared, Thermogravimetric analysis, Powdered x-ray diffraction, and Field emission scanning electron microscopy. The structural characterization indicated that PTA was successfully incorporated into the cavity of MOF-808(Zr) while the structure could remain stable at 350 °C. For this purpose, the produced catalysts were used for the ODS reaction of model fuel injected with BT, DBT, and 4,6-DMBT. The results showed that the highest conversion of DBT is obtained using PTA@MOF-808(Zr)-0.5H as an efficient catalyst in acidic media employing hydrogen peroxide. An improvement in the conversion rate of DBT was achieved at nearly 100% efficiency within a short time. Besides, the catalyst demonstrated high conversion efficiency and therefore may be potentially used for hydrogen generation and storage.
