| description | <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.
