Abstract

The two-step water splitting reaction with perovskite type manganese metal oxide (La_xSr_1-xBO_3-δ or La_xCa_1-xBO_3-δ, B=Mn, Co, Cr, Al) is investigated for solar hydrogen production. The various samples were prepared by modified Pechini method. The maximum amounts of evolved H₂ and O₂ gases were obtained at the La_0.5Sr_0.5MnO_3-δ in the La_0.5Sr_0.5BO_3-δ and La_0.5Ca_0.5BO_3-δ samples. The tolerance factor of La_0.5Sr_0.5MnO_3-δ is very close to 1, it is suggested that the perovskite structure of the compound is most stable. Also, the huge amount of O₂ gas evolution was obseved with La_0.7Ca_0.3CoO_3-δ, however, the reactivity of the reduced sample was decreased in the H₂-generation reaction because of eliminating stability of the sample.
