Fig. 3. (a) Photocurrent density versus time (j–t) plots for NiO assemblies with three 10 s dark–light (one sun illumination) cycles with an applied bias of –0.54 V vs. NHE in 0.1 M in LiClO4 acetonitrile under 1 atm CO2. (b) Photocurrent response of NiO|-DA-RuCP22+-Re(i), over a 20 min period under the same conditions as described for (a).
