Iron oxide functionalised MIL-101 materials in aqueous phase selective oxidations

A highly active Fe containing MIL-101 material has been prepared by using a simple microwave-assisted deposition methodology. The material, characterized by several techniques including N2 physisorption, XPS and TEM, was found to have a significantly enhanced acidity due to the incorporation of ca. 2 wt.% Fe in the form of hematite Fe2O3 phase. Fe/MIL-101 exhibited excelling activities in aqueous phase oxidations of alcohols and alkenes using hydrogen peroxide as green oxidant.
