A novel AgO/ZnO/HY‐zeolite bimetallic nanocatalyst was designed and synthesized by an impregnation method. The purpose of this nanocatalyst was to remove dibenzothiophene as the primary sulfur content from a model light gasoil in a catalytic oxidative desulfurization (ODS) process. The characteristics of the synthesized nanocatalyst were determined by Fourier transform IR spectroscopy, Brunauer‐Emmett‐Teller analysis, scanning electron microscopy, and X‐ray diffraction. The ODS study revealed high sulfur conversion under optimal ODS reaction conditions and very good reusability of the catalyst after recycling five times.
