Abstract

A highly active catalyst H4[?-SiW12O40]/Zr based polyoxometalete Keggin type was prepared by wet impregnation method and was characterized by FTIR spectroscopy, X-ray diffractometer, surface textural property by SEM, and analysis of porosity by BET method. H4[?-SiW12O40]/Zr was successfully synthesized and showed uniform properties with block solid structure which was applied as heterogeneous stable catalyst for oxidative desulfurization of benzothiophene under simple and mild condition using H2O2 as oxidant. Facile conversion of benzothiophene to sulfone by using heterogeneus                    H4[?-SiW12O40]/Zr catalyst up to 99% was observed to show the active catalytically. Keggin             H4[?-SiW12O40]/Zr cage structure after reaction was different from fresh catalyst which was indicated by the instability of H4[?-SiW12O40]/Zr  under reaction condition. © 2015 BCREC UNDIP.
