PURPOSE:To obtain H2 and O2 by irradiating light on an aqueous soln. contg. a mixed complex consisting of a hexacyano-metallic complex and a salt of a transition metal and a tris(polypyridyl) metallic complex to cause the photolysis of the water. CONSTITUTION:An aqueous soln. contg. a hexacyano-metallic complex having an element belonging to the Va, VIa, VIIa or VIII group in the periodic table such as V, Cr, Mn, Fe or Co as the central metal and a salt of a metal belonging to the VIa, VIIa, VIII or I b group is prepared. Ferrous chloride, manganese chloride, cupric chloride or the like is used as the metallic salt. A tris(polypyridyl) metallic (II) complex of a metal belonging to the VIII group such as Prussion blue prepared from hexacyano-iron (III) potassium and an aqueous soln. of a ferrous salt is dissolved in said aqueous soln., and the pH of the resulting aqueous soln. is adjusted to the acidic side. Light is irradiated on the acidic soln. from a light source such as a W lamp to decompose the water into H2 and O2 usually at room temp. |
