CdS is a well-known and important visible-light responsive photocatalyst for overall water splitting. However, the serious photocorrosion property limits its application in photocatalysis. Through modification TiO₂ thin film over CdS surface, TiO₂/CdS photocatalyst exhibited an obviously enhanced photocatalytic stability. The H₂ evolution rate (3.074 μmol h⁻¹ g⁻¹) of modified Pt-TiO₂/CdS under visible light toward overall water splitting was almost 6 times higher than that of CdS sample (0.534 μmol h⁻¹ g⁻¹). The application of artificial gill in photocatalytic overall water splitting system removed the newly formed oxygen from catalyst surface mainly inhibiting the hydrogen and oxygen back recombination to water and preventing the oxygen led oxidation or photocorrosion. By these two strategies, we fulfilled visible light induced overall water splitting in CdS dispersion and achieved satisfied stability during reaction.
