The role of a photocatalyst in the sonophotocatalytic reaction of water was investigated using TiO₂ photocatalysts. Based on this investigation, sonophotocatalytic water splitting using visible light was attempted. BiVO₄ is a visible light-sensitive material and this material is one of the candidates for O₂ evolution photocatalyst. For example, O₂ is evolved from H₂O₂ solution by photocatalytic reaction under visible light irradiation. On the other hand, H₂ is produced together with H₂O₂ from water by irradiation of ultrasound. Thus, it is expected to obtain H₂ and O₂ from water when these two reaction systems are combined. Simultaneous irradiation of visible light and ultrasound was tried to perform. As the result, liquid water was decomposed to H₂ and O₂ continuously and stoichiometrically.
