The decomposition of water by sunlight is a fascinating concept in view of today's energy debate. Evolution of O 2 according to the equation (1) or (2) could be a first step in this direction. Suitable redox catalysts are PtO 2 and IrO 2 . Ce 3+ and Ru(bpy) 3 2+can be photochemically reoxidized with evolution of H 2 .
