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.
已对组成为La1-xCaxMnO3(LCM)的钙钛矿氧化物进行了研究,以分别通过水和二氧化碳的热化学分解来制取氢气和一氧化碳。该研究是与La1-xSrxMnO3、CeO2及其他氧化物对比进行的。LCM体系在高温析氧以及将二氧化碳还原为一氧化碳、将水还原为氢气方面表现出优异特性。La0.5Ca0.5MnO3取得了最佳结果,与包括二氧化铈在内的其他氧化物相比,其性能值得关注。LCM的正交结构似乎是一个关键因素。
