(a) LSV curves recorded for pristine ZnO, ZnO/Au and ZnO/Au/Al2O3 (5 cycles) photoanodes with a scan rate of 10 mV/s in the applied potentials from −1.0 to 1.5 V (vs Ag/AgCl) under AM 1.5 G simulated solar light. (b) Transient photocurrent density for ZnO/Au/Al2O3 (5 cycles) photoanodes measured at 0 V vs Ag/AgCl in 0.5 M Na2SO4 electrolyte (pH = 7). (c) Chronoamperometric I-t curves collected at 0.5 V vs Ag/AgCl for the three different photoanodes under visible light (>420 nm). (d) Photoconversion efficiency of the PEC cell with three different photoanodes as a function of the applied photential (vs RHE).
