【 摘 要 】

Amphiphilic polyoxometalate was successfully immobilized on the surface of amino-functional ordered meso/macroporous silica materials by the precipitation method and used as a catalyst for oxidative desulfurization (ODS). The as-prepared catalyst exhibited highly ordered meso/macroporous structure with the amphiphilic polyoxometalate covered on the amino-functional SiO2. The nanocomposite was used as catalyst in ODS process which can remove dibenzothiophene (DBT) in model fuel within 2 h. Moreover, the recyclability of catalysts was carried out and it was related to the increasing amino group on surface of catalyst.
