Abstract: In a first aspect, the present invention is directed to a process for forming a metal alloy catalyst. Another aspect of the present invention is directed to a process for oxidizing a substrate that includes contacting a substrate with an oxidant in the presence of a metal alloy catalyst to form one or more carboxylic acids. Suitable substrates include sugars, polyols, furfural alcohols, and polyhydroxycarboxylic acids. The oxidation process may use the alloy catalyst formed from the process of the first aspect of the invention.
