CATHODE PRODUCTION METHOD FOR ELECTRO-CHEMICAL PROCESSES WITH HYDROGEN DEVELOPMENT

摘要

The process comprises application to a metal support, of a Raney nickel coating for embedding in its porous structure of an electrocatalytic film. This intermediate layer is firmly bonded to the film by cathodic polarisation of the electrode for a short time in a Watts bath. The cathodes facilitate electrolysis of halogenated derivatives of alkali metals, employing solns. of alkali metal hydroxides and permeable or ion exchange membranes.
