Abstract

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.
