Abstract
Disclosed is a method of treating a porous Raney nickel electrode having pyrophoric properties to eliminate such properties while maintaining the catalytic properties of the electrode. The method includes coating an active porous Raney nickel electrode with an aqueous solution consisting essentially of 4 to 50 weight percent alkali metal hydroxide and exposing the coated electrode to air for a period of time sufficient to eliminate the pyrophoric tendencies of the electrode. Also disclosed is a method of activating and depyrophorizing a nickel-aluminum coated electrode by immersing the electrode in an aqueous solution of alkali metal hydroxide to leach the aluminum and activate the electrode and then maintaining a film or coating of the alkali metal hydroxide upon the leached electrode and exposing the coated electrode to air until the electrode is depyrophorized.
