Photocatalytic overall water splitting under a two-step photocatalytic (Z scheme) system was studied with layered perovskite H1.9K0.3La0.5Bi0.1Ta2O7 (HKLBT) and Pt/WO3 used as the hydrogen and oxygen evolution photocatalysts, respectively. The influence of the redox mediator species and the concentration of the redox mediator was investigated. The results showed that overall water splitting (H2/O2 volume ratio: 2:1) was achieved using Fe2+/Fe3+ as the redox mediator, where the hydrogen and oxygen evolution rates reached 66.8 and 31.8 μmol·h-1 (H2/O2 volume ratio: 2.1:1), respectively. A very high concentration of the redox mediator is unable to improve the photocatalytic activity because it is blocked by the carrier mediator redox rate based on the activity of the photocatalysts.
