Abstract
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 results 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.
