Abstract:
The presence of sulfur compounds in diesel fuel leads to the emission of SO2, which causes the air pollution. Dibenzothiophene (DBT) is a common sulfur compound which is hardly removed by a traditional desulfurization process. In this study, the TiO2-SiO2 composite was prepared by two different synthesis methods: sol-gel (SG) and wet impregnation (WI). They were then used as photocatalysts for removing dibenzothiophene in model fuel via oxidative desulfurization process, in which DBT would be oxidized to dibenzothiophene sulfone (DBTO2). The photocatalysts were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEM) and N2 adsorption-desorption techniques. The catalytic results showed that the use of the two synthesis methods produced high activity photocatalysts for the removal of dibenzothiophene under UV irradiation. However, the TiO2-SiO2 (SG) composite exhibited higher catalytic activity than the TiO2-SiO2 (WI) composite. Specifically, the percentages of dibenzothiophene removal after 60 min irradiation using TiO2-SiO2 (SG) and TiO2-SiO2 (WI) as photocatalysts were 100 percent and 84 percent, respectively. This result agreed well with the XRD and FTIR analysis in which sol-gel method provided better crystalline TiO2 on the surface of SiO2 than wet impregnation method, therefore reduced the recombination centers caused by defects in the crystal structure.
