一种“双帽Keggin型”磷钒酸盐在温和的反应条件下以分子氧为氧化剂氧化二苯并噻吩至二苯并噻吩砜的反应中表现出很高的催化活性。用溶剂萃取或者选择吸附等方法可轻易地将反应产生的二苯并噻吩砜从油品中除去。这提供了一种新型的分子氧为氧化剂的超深度氧化脱硫方法。

A bicapped Keggin structure vanadophosphate showed high catalytic activity in the oxidation of dibenzothiophene (DBT) to sulfone using molecular oxygen as oxidant under mild reaction condi-tions. This is a promising approach to the ultra-deep desulfurization of fuels (e.g. diesel) as sulfones can be removed from the fuel by extraction or selective adsorption.
