The visible-light-induced reduction of methyl viologen was found to occur in water-swollen cation-exchange resin, which adsorbed both Ru(bpy)32+ and methyl viologen (RMCA resin) with the aid of triethanolamine (TEA) as a donor.With illumination, the generation of hydrogen peroxide procceds in an oxygenated TEA solution containing RMCA resin.Hydrogen peroxide is produced via the superoxide ion, which is itself formed by the reaction of methyl viologen radical in the resin with the oxygen molecule in the bulk of the solution.The Ru(bpy)32+-photosensitized reaction processes leading to the generation of methyl viologen radical and hydrogen peroxide in the heterogeneous systems are discussed on the basis of the results obtained.
