Photocatalytic oxidation desulfurization has become a research hotspot in recent years because of mild reaction conditions,less energy consumption and high selectivity.In this paper,TiO2 was loaded onto SBA-15 molecular sieves and sensitized with organic dyes (2,9-dichloroquinacridone,DCQ) to extend its spectral response range from ultraviolet light to visible light.The catalyst DCQ-X％TiO2@SBA-15 was characterized by BET measurements,X-ray diffraction,Fourier transform infrared spectroscopy and Ultraviolet–visible diffuse reflection spectra,and then it was applied for photocatalytic oxidation desulfurization of gasoline.The effects of different catalytic systems,TiO2 con-centration,catalyst dosage,and different model sulfur compounds on catalytic desulfurization performance were investigated.Experimental results show that DCQ-TiO2@SBA-15 has a better performance than the unsensitized TiO2@SBA-15,and the desulfurization rate can reach up to 96.1％in a reaction time of 90 min.
