Abstract

Redox reactivity of La_(1-x)Sr_xMnO₃ (LSM) perovskites towards a solar thermochemical CO₂ 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 O₂ released (n_O₂) and CO produced (n_CO) by each LSM perovskite. Higher n_O₂ by each LSM perovskite, as compared to the n_CO during the first cycle. The n_O₂ is decreased, and the re-oxidation capacity of each LSM perovskite is improved from cycle one to three. In terms of the average n_O₂ and n_CO from cycle 2 to cycle 10, the La_0.60Sr_0.41Mn_0.99O_2.993 (214.8 μmol of O₂/g·cycle) and La_0.30Sr_0.70Mn_0.99O_2.982 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_0.88Sr_0.11Mn_1.00O_2.980) is recorded to be higher than that of the widely studied CeO₂ material.
