Abstract

H3PW12O40/ZrO2–SiO2 catalyst was successfully prepared by immobilizing phosphotungstic acid (H3PW12O40, HPW) on zirconia-modified silica and employed as a catalyst for oxidative desulfurization (ODS). Under the optimal reaction conditions, the sulfur removal rate from dibenzothiophene was nearly 100%. In addition, the catalyst can be recycled up to 19 times without notable reduction in catalytic activity for the ODS process. The HPW/ZrO2–SiO2 catalyst shows excellent catalytic activity for oxidative reactions, due to the strong interaction between the active HPW and ZrO2–SiO2 support.
