| 概要 |
Ordered double perovskite oxides(A_2BB'O_6, AA'BB'O_6) which contained W, Ta, and Ti were synthesized, and the applicability of the oxides to photocatalytic reaction was discussed. The stability of th...e oxides strongly depended on the constituent atoms, especially B-site cations. Ta-, Nb- and Ti-containing perovskites were stable O_2 evolution in Ag^+ ion-containing aqueous solution. Among the perovskite oxides, La_2ZnTiO_6 showed catalytic activity for the latter reaction and the rate for O_2 evolution normalized by catalyst surface area was one third of that of TiO_2.続きを見る
