Effect of A-/B-site doping on oxygen non-stoichiometry, structure characteristics, and O2 releasing behavior of La1−xCaxCo1−yFeyO3−δ perovskites
Oxy-fuel combustion is one of the proposed technologies with the potential to achieve zero CO2 emission. La1−xCaxCo1−yFeyO3−δ (LCCF) perovskites are promising materials with high selectively for oxygen. In this study, the oxygen non-stoichiometry of perovskites LCCF was investigated by means of iodometric titration. LCCF was prepared using the liquid citrate method, and the phase structures were i
