Abstract
Metal electrodes are prepared by contacting a basis-metal electrode with a solution which contains an alloying element compound, said basis-metal electrode comprising a basis-metal which is present in a finely divided or porous state and is selected from the group consisting of the noble metals from the Groups IB, IIB or VIII of the Periodic Table of the Elements or an alloy of at least one of the metals, said alloying element being selected from the group consisting of an element from Groups IIIA, IVA, VA, VIA, VIII, IB, IIB, VIIB or combinations thereof of the Periodic Table of the Elements; and reducing in situ said alloying-element compound to form the free-alloying element whereby said alloying element forms an alloy with said basis-metal.
