By incorporating H3PW12O40(HPW) heteropolyacid into mesoporous TUD-1 materials, a series of HPW-TUD-1 catalysts were synthesized. Nitrogen adsorption-desorption isotherm, XRD and FTIR characterizations showed that these catalyst exhibited mesoporous structure, and HPW presented in the catalysts with Keggin structure. The catalytic performances of the HPW-TUD-1 catalysts were tested through the oxidative desulfurization (ODS) process of dibenzothiophene (DBT) model oil. The results showed that the obtained 20HPW-TUD-1 catalyst displayed excellent catalytic activity and recover ability for ODS. The desulfurization rate of DBT reached up to 98.1%, and almost no catalytic activity loss was observed after three recycles of the catalyst.
