Photocatalytic Water Oxidation on WO3 Electrodes: Influence of Tungsten Oxide Loading

Figure 4-11: Photocurrent density vs. time curves of (a) WO3-0, (b) WO3-0.62, (c) WO3-1.2, (d) WO3-2.5, (e) WO3-5, and (f) WO3-7.5 electrodes during photocatalytic water oxidation under visible light irradiation (λ > 450 nm, 100 mWcm-2) in a 0.1 M phosphate buffer solution at pH 6.0, at a static potential of 0.68V vs. Ag/AgCl (1.23 V vs. RHE).
