【 摘 要 】

A highly active catalyst H₄[α-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[α-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[α-SiW₁₂O₄₀]/Zr catalyst up to 99% was observed to show the active catalytically. Keggin             H₄[α-SiW₁₂O₄₀]/Zr cage structure after reaction was different from fresh catalyst which was indicated by the instability of H₄[α-SiW₁₂O₄₀]/Zr  under reaction condition. © 2015 BCREC UNDIP.
