文摘

A core-shell structured Fe2O3/ZrO2@ZrO2 nanomaterial is synthesized by a combination of nanocoating and impregnation methods. The evolution of iron oxides to metallic iron in Fe2O3/ZrO2@ZrO2 is followed by in situ XRD as a function of temperature. Fe2O3/ZrO2@ZrO2 shows superior redox activity, excellent structural stability and strong capability to resist sintering in CO2 conversion to CO compared to the material without coating.
