The desulfurization of oil must be resolved as soon as possible due to a variety of issues, including environmental contamination and protection regulations. It was believed that oxidative desulfurization (ODS) was the most promising method. In this research, metal oxide-based layered double hydroxides (TiO2@Ni-Al and ZnO@Ni-Al) were effectively synthesized for the ODS of 4-methyldibenzothiophene (4-MDBT). TiO2@Ni-Al and ZnO@Ni-Al exhibited superior catalytic performance and high recycling capacity, achieving a 99% removal rate after five reactions in 30 min. The heterogeneous catalyst TiO2@Ni-Al/ZnO@Ni-Al is easy to separate and recover from a reaction system. Increased temperature facilitates the transformation of 4-MDBT into 4-MDBTO2. The influence of H2O2's rapid decomposition rate, which can inhibit oxidation reactions, reduces the catalytic activity as the temperature increases. 4-MDBT Sulphur removal on TiO2@Ni-Al and ZnO@Ni-Al is 99.48 and 99.51%, respectively. TiO2@Ni-Al and ZnO@Ni-Al have great potential for use in the industry based on these results. Copyright © 2023 by Authors, Published by BCREC Group.
