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

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.
