Abstract

The effects of the metal ion addition to SrTiO₃ to the overall H₂O splitting were investigated to improve the photocatalytic activity. The addition of metal ions was carried out by impregnation method. The preparation condition of metal ion added SrTiO₃ was examined with applying Na⁺ ion as additive and SrTiO₃ prepared by polymerizable complex method. The photocatalytic activity was markedly improved by the addition of Na⁺ ion and calcined above 1173 K. The preferable state of the photocatalyst was Na ion (2 atm%) added SrTiO₃ obtained by calcination at 1273 K and the photocatalytic activity with a Rh_0.3Cr_1.7O₃ (Rh:0.3 wt%) co-catalyst was 16 mmol/h for H₂ and 8 mmol/h for O₂ production. The apparent quantum yield (AQY) was 16% under the irradiation of 360 nm. The photocatalytic performance of Na⁺ ion added various SrTiO₃ and the effects of various metal ion addition to SrTiO₃ to the photocatalytic activity of the overall H₂O splitting were investigated to discuss the influence of the added metal ions to the photocatalytic activity.
