(a) H2 and O2 evolution on the platinum cathode and Fe2O3/GaN anode, respectively, during 50 h of zero-bias PEC characterization. Comparison of the (b) H2 evolution at the cathode and (c) photocurrent of the PEC cell during the fifth round of characterization (40–50 h) of the Fe2O3/GaN anode, and the unique characterization of the bare GaN anode (0–10 h).
