Abstract
A cathode for the electrolysis of brine for the production of chlorine and caustic soda, whereby chlorate ions are produced, comprises a coating of e.g. Nickel alloyed with a metallic sacrificial component, the latter being leached out by a soltuion of sodium hydroxide. The remaining sodium hydroxide within the pores of the leached nickel coating is transformed into iron hydroxide upon application of an iron salt onto the nickel coating. The iron hydroxide acts as a suppressor for the excessive formation of chlorate ions in the caustic soda solution of the electrolysis cell.
