Fig. 7. (Top) Plots of the amounts of the reduction products after 30 min of photo-irradiation (400 W Hg lamp, λ > 400 nm) versus the concentration of trans(Cl)–Ru(bpy)(CO)2Cl2 in CO2-saturated DMA/water (9 : 1, v/v) in the presence of [Ru(4dmbpy)3](PF6)2 (0.50 mM) and BNAH (0.10 M): CO (○), HCOO– (■), H2 (Δ) and CO + HCOO– (+). (Bottom) Plots of the CO/HCOO– ratio versus the concentration of trans(Cl)–Ru(bpy)(CO)2Cl2. The curves represent the theoretical fittings based on the kinetic analyses (see eqn (3) and (4)).
