[ $Sr_2Ta_2O_7$ ], a layered perovskite compound, has been reported to possess most excellent photocatalytic properties among the layered perovskite materials. Recently, we have demonstrated that $Ba_5Ta_4O_{15}$ that was prepared under a mol ratio of Ba: Ta=1:1 has high photocatalytic performance as well as $Sr_2Ta_2O_7$. In this study, the photocatalyst samples with a mol ratio of Sr: Ba: Ta = (1-x): x: 1 were prepared. The maximum photocatalytic performance was obtained for x= 0.2, which is three times as high as that of undoped $Sr_2Ta_2O_7$.
