ABSTRACT:
The invention relates to the production of multilayer electrodes on valve metal substrates, through a method comprising the application in alternate cycles of a solution containing precursors of noble metals, and of a second solution containing transition metals capable of forming protective coatings. The resulting electrodes are useful in several applications, among which copper and other metal plating and the treatment of waste or tap water.
