| description | <p dir="ltr">Redox reactivity of La<sub>(1-x)</sub>Sr<sub>x</sub>MnO<sub>3</sub> (LSM) perovskites towards a solar thermochemical CO<sub>2</sub> splitting (CS) cycle is investigated. The LSM perovskites are synthesized via a solution combustion synthesis (SCS) method using glycine as the reducing agent. Multiple analytical techniques are used for the structural characterization of the LSM perovskites. Thermogravimetric thermal reduction (TR) and CS cycles (in three sets: one, three and ten cycles) are conducted to estimate the amounts of O<sub>2</sub> released (n<sub>O2</sub> ) and CO produced (n<sub>CO</sub>) by each LSM perovskite. Higher n<sub>O2</sub> by each LSM perovskite, as compared to the n<sub>CO</sub> during the first cycle. The n<sub>O2</sub> is decreased, and the re-oxidation capacity of each LSM perovskite is improved from cycle one to three. In terms of the average n<sub>O2</sub> and n<sub>CO</sub> from cycle 2 to cycle 10, the La<sub>0.60</sub>Sr<sub>0.41</sub>Mn<sub>0.99</sub>O<sub>2.993</sub> (214.8 μmol of O2/g⋅cycle) and La<sub>0.30</sub>Sr<sub>0.70</sub>Mn<sub>0.99</sub>O<sub>2.982</sub> perovskites (342.1 μmol of CO/g⋅cycle) are observed to have the uppermost redox reactivity. The redox reactivity of all the LSM perovskites (except for La<sub>0.88</sub>Sr<sub>0.11</sub>Mn<sub>1.00</sub>O<sub>2.980</sub>) is recorded to be higher than that of the widely studied CeO<sub>2</sub> material.</p><h2>Other Information</h2><p dir="ltr">Published in: Fuel<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1016/j.fuel.2020.119154" target="_blank">https://dx.doi.org/10.1016/j.fuel.2020.119154</a></p> |
