Photoelectrochemical performance of a WO3-NRs/BiVO4+CoPi photoanode measured by the two-electrode method under the bias of 1 V.
(a) IPCE measured at 25 °C (blue) and 50 °C (red), (b) I-V characteristics measured under chopped light at 1 sun, 25 °C and at 3 suns, 50 °C. (c) and (d) gas production rates (circles), faradaic efficiencies (rectangles) and theoretical gas production rates (dashed lines) of O2 (black) and H2 (red) for 1sun, 25 °C (c) and for 3 suns, 50 °C (d) with simultaneously recorded Jp-t profiles.
