| Partially sulfided nanostructures were synthesized by direct sulfurization of α-MoO3 nanorods using a mixture of H2S/H2, 15 vol%, at several temperatures (400, 500, 600, 700, and 800 °C). These materials were tested as catalysts in the hydrodesulfurization (HDS) of dibenzothiophene (DBT) and characterized by specific surface areas using the expression developed by Brunauer, Emmett, and Teller (BET equation), x-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The TEM images show a gradual evolution from a smooth surface to a rough material, presenting some type of holes all over the particles, but keeping their rod-like structure throughout sulfidation. The results of evaluating the catalysts in the HDS of DBT showed that the best temperature for sulfidation is 500 °C. In all samples, a higher selectivity for hydrogenation over sulfur removal was observed. | |
