Abstract

Redox catalysts having surface medication, methods of making redox catalysts with surface modification, and uses of the surface modified redox catalysts are provided. In some aspects, the redox catalysts include a core oxygen carrier region such as CaMnO, BaMnO, SrMnO, MnSiO, MnMgO, LaSrO, LaSrFeO, CaTiMnO, PrO, manganese ore, or a combination thereof; and an outer shell having an average thickness of about 1-100 monolayers surrounding the outer surface of the core region. The outer shell can include, for example a salt selected such as LiWO, NaWO, KWO, SrWO, LiMoO, NaMoO, KMoO, CsMoO, LiCO, NaCO, KCO, or a combination thereof.
