DEFINITION

Classification: 205/534

Raney metal containing coating (e.g., Ni-Al alloy, etc.):

(under subclass 532) Subject matter wherein the electrode has at least one Raney metal containing coating.

(1) Note. Raney metal is an alloy of any two or more metals having the property of forming a catalytically active porous surface upon the leaching of an inactive soluble component metal (sacrificial metal) from the alloy, usually by a strong base such as sodium hydroxide, to leave an active metal. Some specific Raney metals are, for example, Raney silver and

Raney Cobalt. This subclass includes both the alloy or the active catalyst produced by dissolving out the sacrificial metal.
