Abstract Developing highly dispersed species has been regarded as an effective approach to achieve high catalytic performance. In this work, tungsten-containing precursor were control confined in porous channel of SBA-15. Profiting from the ionic liquid, quantum dots (such as WO3 QDs) in SBA-15 with highly dispersion can be obtained after thermal treatment. This prepared tungsten-based QDs confined SBA-15 materials can deliver excellent catalytic performance for oxidation desulfurization, in which 100 % DBT can be removed in 1 h. The oxidation desulfurization reaction mechanism is also explored and main active specie is determined to be ·OH. This strategy provides an accessible pathway for preparation of other catalysts with highly dispersed species.
