Figure 4. (A) LSV curves of Zn0.5Cd0.5S in 0.1 M KOH solution with and without glycerol under dark and Xenon lamp illumination; (B) Transient response to the light irradiation at 1.2 V vs. RHE in 0.1 M KOH solution with 0.1 M glycerol; (C) Photocurrent density and calculated charge with increasing reaction time (insets are the photos of the working electrode before and after reaction; (D) Glycerol conversion and glyceric acid selectivity. LSV: Linear sweep voltammetry; RHE: reversible hydrogen electrode.
