Figure 7. PEC properties of anatase TiO2 and SrTiO3 photoanodes with an irradiation area of 2 cm2 in a vapor-fed water splitting system (wavelength: 365 nm and irradiance: 40 mW cm-2). Impact of applied voltage (V vs. cathode) on (A) photocurrent response and (B) rate of H2 formation in the cathode compartment and O2 and CO2 formation in the photoanode compartment. (C) Enlarged view of the product formation rate at 0.3 V vs. cathode. Reproduced from ref.[13] with permission from the Royal Society of Chemistry.
