Room temperature oxidative desulfurization with MoO3 subnanoclusters supported on MCM-41

Abstract

Subnano MoO₃/MCM-41 was successfully prepared through doping (NH₄)₆Mo₇O₂₄ in the synthesis process of MCM-41. The morphology of MoO₃/MCM-41 was visually observed by TEM and HADDF-STEM. N₂ sorption, XPS and Raman were further applied to investigate the structure of the material. MoO₃/MCM-41 was used in the oxidative desulfurization process with tert-butyl hydroperoxide as oxidant. MoO₃/MCM-41 showed outstanding catalytic activity and recycling ability at room temperature.
