摘要:
Processes for making multinary bulk and thin film alloys with nanometer-scale grains are disclosed. An electroless process includes contacting a substrate with a bath within a sealed pressure vessel; and heating the sealed pressure vessel for a time and at a temperature under an autogeneous pressure effective for plating a film of an alloy with nanometer-scale grains onto a contacted portion of the substrate; wherein the bath is formed from one or more salts comprising each constituent element of the alloy, an organic medium, and a reducing agent. The bulk and thin film alloys may be useful in applications requiring high surface area materials or protection from corrosion such as for catalysts and battery cathodes.
