The Utilization of Rice Husk as Both the Silicon Source and Mesoporous Template for the Green Preparation of Mesoporous TiO/SiO and Its Excellent Catalytic Performance in Oxidative Desulfurization.

In recent years, TiO-based catalysts have received extensive attention from researchers for their excellent oxidative desulfurization (ODS) performances. In this paper, a series of mesoporous TiO/SiO catalysts with different TiO loadings are prepared, using an incipient wetness impregnation method with agricultural waste rice husk as both the silicon source and mesoporous template and tetrabutyl titanate as the titanium source. The effect of different TiO loadings on the ODS performance of the samples is investigated, and the appropriate TiO loading is 2.
