This work provides a way to design oxygen carriers for chemical looping. Starting from Prussian blue microcubes, Zr-promoted Fe-based materials are developed for the conversion of CO 2 into CO. Thermally induced oxidative decomposition of ZrO 2-coated Prussian blue under the protection of the firstly formed ZrO 2 shell leads to the formation of hollow structured materials. Detailed activity tests and in-situ characterization are used to investigate the relationship between material structure, stability and CO yield from CO 2 conversion. Throughout one hundred H 2-CO 2 redox cycles, 10% Fe 2 O 3/ZrO 2 exhibits a 27 times higher CO space-time yield (86 m m o l∙ s-1∙ k g F e 2 O 3-1) than unpromoted, yet hollow structured Fe 2 O 3. This superior performance derives from the dual role that ZrO 2 plays: protecting the structure, thereby improving the iron oxide sintering resistance, and facilitating the reduction of iron oxide during redox cycles. The hollow structure and the interaction between Fe 2 O 3 and ZrO 2 are the main reasons for the enhanced redox activity.
