The present study exemplifies novel applications of iron and manganese containing mixed oxides for methane partial oxidation, oxidative dehydrogenation (ODH) of ethane, water-splitting, and CO2 reduction. A number of redox catalysts composed of iron and/or manganese oxides are synthesized and characterized. Rational strategies to improve the redox activity, product selectivity, and/or water-splitting and CO2 reduction conversions are investigated through the assistance of spectroscopy and ab-initio calculation tools. Compared to traditional heterogeneous catalysts, the redox catalysts in the current study show the potential to be more selective. They also possess excellent redox stability. Close to 100% water and CO2 reduction efficiencies are shown to be achievable through rational selection of mixed metal oxide based redox catalysts.
