Performance of TiO2// electrodes. (a) LSV characteristic curves (A) in the dark and (B) under AM 1.5 illumination. (b) Amperometric photoresponses obtained with on/off light cycles at 100 mW cm−2 at a fixed potential of −0.9 V, (c) photoconversion efficiency versus applied voltage (, with respect to OCP), and (d) IPCE spectra. Electrolyte: 2M Na2S + 0.25 M Na2SO3 (pH 13.0).
