الملخص:<p dir="ltr">The redox reactivity of the Li-, Mg-, Ca-, Sr-, Ba-, and Sn-doped ceria (Ce<sub>0.9</sub>A0.<sub>1</sub>O<sub>2</sub>−<sub>δ</sub>) toward thermochemical CO<sub>2</sub> splitting is investigated. Proposed Ce<sub>0.9</sub>A0.<sub>1</sub>O<sub>2</sub>−<sub>δ</sub> materials are prepared via co-precipitation of the hydroxide technique. The composition, morphology, and the average particle size of the Ce<sub>0.9</sub>A0.<sub>1</sub>O<sub>2</sub>−<sub>δ</sub> materials are determined by using suitable characterization methods. By utilizing a thermogravimetric analyzer setup, the long-term redox performance of each Ce<sub>0.9</sub>A0.<sub>1</sub>O<sub>2</sub>−<sub>δ</sub> material is estimated. The results obtained indicate that all the Ce<sub>0.9</sub>A0.<sub>1</sub>O<sub>2</sub>−<sub>δ</sub> materials are able to produce steady amounts of O<sub>2</sub> and CO from cycle 4 to cycle 10. Based on the average <i>n</i><sub><em>O2</em></sub> released and n<sub><em>CO</em></sub> produced, the Ce<sub>0.899</sub>Sn<sub>0.102O2.002</sub> and Ce<sub>0.895Ca0.099O1.889</sub> are observed to be the top and bottom-most choices. When compared with the CeO<sub>2</sub> material, all Ce<sub>0.9</sub>A0.<sub>1</sub>O<sub>2</sub>−<sub>δ</sub>materials showed elevated levels of O<sub>2</sub> release and CO production.</p><h2>Other Information</h2><p dir="ltr">Published in: Journal of Materials Science<br>License: <a href="https://creativecommons.org/licenses/by/4.0" target="_blank">https://creativecommons.org/licenses/by/4.0</a><br>See article on publisher's website: <a href="http://dx.doi.org/10.1007/s10853-020-04875-1" target="_blank">http://dx.doi.org/10.1007/s10853-020-04875-1</a></p>
