Sr- and Co-doped LaGaO_3−δ with high O₂ and H₂ yields in solar thermochemical water splitting

Abstract

Sr- and Co-doped perovskite oxides La_1−xSr<italic>x</italic>Ga_1−yCo_yO_3−δ (LSGC) with controllable oxygen vancancy formation energy (<italic>E</italic>_V) and oxygen vacancy concentration (<italic>−</italic>) are successfully developed to exhibit high O₂ and H₂ yields when reduced at 1350 °C and re-oxidized at optimized 400−1100 °C.
