High-purity hydrogen production via water splitting over BaFeO_3-δ (BF)-based perovskites was studied, where reduction/oxidation temperatures were paired at 500/500, 700/700 and 900/900 °C. Ba_0.95La_0.05FeO_3-δ (BLF) yielded the highest H₂production, ca.1310 μmol/g at 900 °C. Adding either La or Gd into BF established a cubic phase structure, allowing a higher concentration of oxygen deficiencies. Sintering was observed over all catalysts, which became more obvious when the oxidation temperature and number of cycles were increased. The apparent activation energy and pre-exponential factor for BLF oxidation in the presence of H₂O were estimated to be 47.4 kJ/mol and 0.18 s⁻¹, respectively.

研究了通过在BaFeO3 _-δ（BF）基钙钛矿上进行水分解产生高纯度氢的方法，其中还原/氧化温度配对为500 / 500、700 / 700和900/900°C。的Ba _0.95的La _0.05的FeO _3-δ（BLF）产生最高ħ ₂生产，ca.1310微摩尔/克，在900℃。向BF中添加La或Gd建立了立方相结构，从而允许更高浓度的缺氧。在所有催化剂上均观察到烧结，当氧化温度和循环次数增加时，烧结变得更加明显。在H ₂ O存在下，BLF氧化的表观活化能和指数前因子估计为47.4 kJ / mol和0.18 s^-1。
