Contacts that may be highly corrosion resistant, less susceptible to wear, and may be readily manufactured with a process that controls or reduces resource usage. Corrosion resistance and wear performance may be improved by providing a thicker plating that has a reduced tendency to crack and by using materials that act as catalysts. Wear performance may be improved by reducing grain size for a harder plating. An amount of resources needed may be reduced or controlled by using materials that plate well and by using a manufacturing process having a reduced number of steps.

Metastable alloys have recently emerged as high-performance catalysts, extending the toolbox of binary alloy materials that can be utilized to mediate electrocatalytic reactions. In particular, nanostructured metastable ordered intermetallic compounds are particularly challenging to synthesize. Here the present invention is directed to a method for synthesizing sub-15 nm metastable ordered intermetallic Pd31Bi12 nanoparticles at room temperature, in a single step, by pulsed electrochemical deposition onto high surface area carbon supports. The resulting Pd31Bi12 nanoparticles displays a 7 enhancement of the mass activity relative to Pt/C and a 4 enhancement relative to Pd/C for the oxygen reduction reaction (ORR). The high performance of Pd31Bi12 nanoparticles is demonstrated to arise from reduced oxygen binding caused by alloying of Pd with Bi. The isolation of Pd-sites from each other facilitate methanol tolerant ORR behavior.
