In this work, we report that new ODS catalyst consisting of H3PW12O40 (PW) and UiO-66(Zr) was developed without the addition of any solvent. As a result, the catalyst exhibited extraordinary catalytic activity by using H2O2 as oxidant in the ODS reactions of benzothiophene, dibenzothiophene and 4,6- dimethyldibenzothiophene. The TOF number for the removal of DBT reached 221.4 h- 1 at room temperature, which is much higher than that of the reported catalysts. Such outstanding catalytic performance could be mainly attributed to easy accessibility of active sites and the existence of two types of active centers from PW species and defective UiO-66(Zr).Show less >
