Noteworthy performance of La1−xCaxMnO3 perovskites in generating H2 and CO by the thermochemical splitting of H2O and CO2

Abstract

Perovskite oxides of the composition La1−xCaxMnO3 (LCM) have been investigated for the thermochemical splitting of H2O and CO2 to produce H2 and CO, respectively. The study was carried out in comparison with La1−xSrxMnO3, CeO2 and other oxides. The LCM system exhibits superior characteristics in high-temperature evolution of oxygen, and in reducing CO2 to CO and H2O to H2. The best results were obtained with La0.5Ca0.5MnO3 whose performance is noteworthy compared to that of other oxides including ceria. The orthorhombic structure of LCM seems to be a crucial factor.
