Abstract:
A description is given of an excited state photoelectrochemical cell in which the excited state, Ru(bpy) 2+ * 3 (bpy is 2,2′‐bipyridine) is quenched via irreversible electron transfer to Co(NH 3 5 Cl +2 which gives Ru(bpy) 3+ 3 . The oxidizing equivalents in Ru(bpy) 3+ 3 are transferred via an external circuit to a second half‐cell in which OH − is oxidized to O 2 . The variation of photogenerated charge and limiting currents with changes in [Co(NH 3 ) 5 Cl +2 ], time, and other variables are presented in the context of a kinetic model for the cell. Conditions are also described for the operation of the cell as an actinometer which is useful for the wavelength range 360 nm ≦ λ ≦ 580 nm and exhibits reproducibility comparable to that observed with conventional chemical actinometers.
