Heterogeneous Catalytic Oxidative Desulfurization of Dibenzothiophene of Metal Oxide-Mg/Al Layered Double Hydroxide

Mg/Al-TiO ₂ and Mg/Al-ZnO were successfully prepared for dibenzothiophene catalytic oxidative desulfurization. XRD, FTIR, TEM, and BET analyses were utilized to characterize the catalyst. In composites, the distinctive XRD patterns of precursors are still observable. FTIR spectra of the absorption bands at 3448, 1627, 1381, 601, and 547 cm ^− 1 . The TEM pictures of the sample also revealed the almost spherical and hexagonal platelets of Mg/Al-LDH and its composite. Mg/Al LDH, Mg/Al-TiO ₂ , and Mg/Al-ZnO had typical pore sizes of 35.78 nm, 52.81 nm, and 38.37 nm, respectively. The graph of nitrogen isotherms Mg/Al LDH, Mg/Al-TiO ₂ , and Mg/Al-ZnO followed type IV isotherms. In addition. The conversion rates on Mg/Al-ZnO, Mg/Al-TiO ₂ , ZnO, Mg/Al-LDH, and TiO ₂ were 99.34%, 99.50%, 91.20%, 96.29%, and 88.06%, respectively. This work presents alternative materials for the oxidative desulfurization of dibenzothiophene in practical applications.
