  • OXYGEN CARRYING MATERIALS WITH SURFACE MODIFICATION FOR REDOX-BASED CATALYSIS AND METHODS OF MAKING AND USES THEREOF
    Publication number: 20230415124
    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 CaMnO3, BaMnO3-?, SrMnO3-?, Mn2SiO4, Mn2MgO4-?, La0.8Sr0.2O3-?, La0.8Sr0.2FeO3-?, Ca9Ti0.1Mn0.9O3-?, Pr6O11-?, 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 Li2WO4, Na2WO4, K2WO4, SrWO4, Li2MoO4, Na2MoO4, K2MoO4, CsMoO4, Li2CO3, Na2CO3, K2CO3, or a combination thereof.
