Fig. 4. Collector–generator experiment for a TiCl4–mTiO2|DPP-Ru/CDCA electrode prepared by immobilisation in MeOH solution (0.1 mM DPP-Ru and 20 mM CDCA). Conditions: NaOAc buffer (0.1 M, pH 5.6) with NaClO4 (0.4 M), 100 mW cm−2, AM 1.5G, λ > 420 nm, N2 purged, room temperature. (a) Chronoamperometry photocurrent trace of the generator with an applied potential of +0.2 vs. NHE. (b) Chronoamperometry current trace of the collector with an applied potential of −0.6 vs. NHE.
