It has been confirmed that colloidal silica can retard reverse electron transfer in the photochemical system water/ tris (2,2′- bipyridine )ruthenium dication/triethanolamine/zwitterionic viologen . However, the beneficial effect of silica diminishes as the concentration of the electron donor ( triethanolamine ) increases. Substantially higher yields of hydrogen have been obtained with 2,2′,6,6′-tetramethyl-1,1′- di (3-sulfonatopropyl)-4,4′-bipyridinediium which is more stable and has a more favourable potential than previously used electron-transfer agents.

The Other

Unidirectional photocatalytic electron transfer from a hydrophilic electron donor encapsulated in the interior of a liposome, to a hydrophilic electron acceptor on the other side of the membrane, has been achieved using the simple membrane-soluble electron relay 1-methoxy-N-methylphenazinium (MMP+).
