Abstract

PURPOSE: To provide an anode for electrolysis of water of a low oxygen overvoltage and high durability by using ruthenium oxide of small contents of chlorine as an essential component for active components.
CONSTITUTION: Ruthenium chloride is caused to react with an alkali to allow the precipitate of ruthenium hydroxide to form. For example, ammoniac water, ammonium hydroxide or the like is used as the alkali. The formed precipitate is washed by using dechlorinated pure water. The residual amt. of the chlorine after the washing is kept at roughly ≤0.3wt%, more preferably, ≤0.1wt%. The resultant ruthenium hydroxide is converted to ruthenium oxide by heating. The heating temp. is usually about 400W700°C, and the heating time about 1W6hr. Such ruthenium oxide is controlled to about 200 meshes grain sizes, and is mixed with a binder and a surfactant and the mixture is prepared into a paste. This paste is press-stuck by heating to an ion exchange membrane, whereby an anode is formed. The anode is preferably of about 0.01W1,000μ average pore sizes and about 20W95% porosities.
