Abstract

In this study, graphitic carbon nitride (g-C3N4) has been synthesized. The cobalt-doped (CoO/g-C3N4) samples prepared by the impregnation method and their catalytic property were investigated on the ODS process. The structure and components of the prepared samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), nitrogen adsorption-desorption (BET), and Fourier-transform infrared (FT-IR). The impression of parameters such as reaction temperature, oxidant dosage, amount of catalyst, different cobalt contents loaded (5, 15, 30, 45, and 60 wt.%), and reaction time optimized by the Taguchi method. Results demonstrated that under the optimal condition; 65 oC, 0.05ml oxidant, 0.06g catalyst, 45 % of cobalt loading, and 80 minutes, the conversion reached 86.7%. Besides, it revealed that cobalt contents loaded are the most effective parameter in the ODS process. In addition, efficiency decreased sharply by adding cyclohexanone, which demonstrated that it has a strong negative effect on efficiency. Finally, a reaction mechanism for the catalytic oxidation of DBT in the presence of CoO/g-C3N4 was proposed.
