The electrochemical performance of a standalone PEC cell. (a) Hydrogen evolution reaction at NiMo/Si (red), Pt NP/Si (orange), and pristine Si (blue). (b) Overall water-splitting performance. NiMo/Si and Ni foam electrodes are connected in a two-electrode configuration. (c) Evolution of H2 and O2 gas at NiMo/Si and Ni foam electrodes. Gas measurement was carried out by applying a voltage of 2.65 V across the electrodes. Faradaic efficiency approached to 100%. The theoretical H2 (red line) and O2 (black line) amounts was calculated based on the charge passed during electrolysis. All electrochemical experiments were conducted in 0.1 M phosphate buffer (pH 7.0) under simulated AM 1.5 G irradiation (100 mW cm−2).
