Efficient aerobic oxidative desulfurization via three-dimensional ordered macroporous tungsten-titanium oxides

摘要

A series of three-dimensional ordered macroporous (3DOM) W-TiO2 catalysts have been prepared through a facile colloidal crystal template method. The prepared materials characterized in detail exhibited enhanced catalytic activity in aerobic oxidative desulfurization process. The experimental re-sults indicated that the as-prepared materials possessed excellent 3DOM structure, which is beneficial for the catalytic activity. The sample 3DOM W-TiO2-20 exhibited the highest activity in ODS process, and the sulfur removal can reach 98 in 6 h. Furthermore, the oxidative product was also analyzed in the reaction process.
