Figure 5: Time courses of red light-driven water splitting by the hybrid systems.

(a) PSII-Ru2S3/CdS. (b) PSII-Ru/SrTiO3:Rh. Both hybrid systems were dispersed in the Na–phosphate buffer solution with pH 6.0. The light source was a xenon lamp with a long-pass filter (λ>600 nm) and the power density was 150 mW cm−2. All data points represent the average of three independent data sets with s.d.
