| الملخص: | <p dir="ltr">Efficacy of the sol–gel derived Ni-doped Mg-ferrites for an enhanced CO<sub>2</sub> splitting activity is investigated. The results allied with the characterization indicate the formation of nominally phase pure Ni-doped Mg-ferrites with a coarser particle morphology. Ni-doped Mg-ferrites are further tested for multiple thermal reduction as well as CO<sub>2</sub> splitting steps by using a thermogravimetric analyzer. The results associated with the thermogravimetric analysis confirmed that most of the Ni-doped Mg-ferrites attained a steady TR aptitude after crossing the 5th or 6th cycle. Likewise, the CS capability of all the Ni-doped Mg-ferrites accomplished consistency after 4th cycle (except for Ni<sub>0.11</sub>Mg<sub>0.88</sub>Fe<sub>2.01O4.005</sub>). The Ni<sub>0.90</sub>Mg<sub>0.11</sub>Fe<sub>2.04O4.070 </sub>showed the highest amount of O<sub>2</sub> release (117.1 μmol/g cycle) and CO production (210.3 μmol/g cycle) in ten consecutive thermochemical cycles. Besides, Ni<sub>0.29</sub>Mg<sub>0.72</sub>Fe<sub>1.98O3.980</sub> indicated better re-oxidation aptitude (<i>n</i><sub><em>CO</em></sub><i>/n</i><sub><em>O2</em></sub><i> </i>ratio = 1.89) when compared with other Ni-doped Mg-ferrites.</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/s10853-020-04794-1" target="_blank">http://dx.doi.org/10.1007/s10853-020-04794-1</a></p> |
