Chemical utilization of the sun's radiation is very attractive aim. The evolution of oxygen and, on irradiation, hydrogen from water in the presence of redox catalysts are known, but rather slow processes. Colloidal ruthenium and other metals catalyze these reactions better than less finely divided materials.
