title: Room Temperature CO Oxidation over Pt/MgFe2O4: A Stable Inverse Spinel Oxide Support for Preparing Highly Efficient Pt Catalyst.
abstract: MgFe2O4with inverse spinel structure is demonstrated to be an efficient support for constructing practical potential Pt catalyst (Pt/MgFe2O4). The resultant Pt/MgFe2O4exhibits excellent catalytic behavior in CO oxidation under normal temperature and humidity. TOF calculated based on the content of Pt is 0.131 s-1. The excellent performance of Pt/MgFe2O4attributes to the presence of surface undercoordinated lattice oxygens on MgFe2O4support. These oxygens could participate in the initial CO oxidation and then be recovered under O2conditions. Over this Pt/MgFe2O4catalyst, CO catalytic oxidation should mainly follow a redox mechanism.
