Photocurrent responses of photoanodes at a constant bias of 0 V (vs Ag/AgCl). (a) Photocurrent densities of ATO and ATO-H as a function of hydrogenation processing time. Photocurrent response of ATO and ATO-H-10 electrodes irradiated with (b) UV (365 nm) and (c) simulated solar light for 60 s light on. (d) Amperometric I-t curves of ATO and ATO-H-10 electrodes obtained under simulated solar illumination.
