%X It has been confirmed that colloidal silica can retard reverse electron transfer in the photochemical system water/ tris (2,2&#8242;- 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&#8242;,6,6&#8242;-tetramethyl-1,1&#8242;- di (3-sulfonatopropyl)-4,4&#8242;-bipyridinediium which is more stable and has a more favourable potential than previously used electron-transfer agents.
