A photoresponsive electrode was prepared by coating a Nafion film on a indium tin oxide (ITO) electrode incorporating the Ru(bpy)2+3 complex in the film. A photocurrent was induced at the coated electrode dipped in an aqueous electrolyte in the presence of oxygen. The action spectrum showed that the photocurrent is based on the reaction between O2 and the excited Ru complex. Viologen molecules present as a solute or as the second film on the top of the Nafion[Ru(bpy)2+3] film increase the induced photocurrent by about a factor of two by working as a mediator between the excited Ru(bpy)2+3 and O2.
