RUTHENIUM-TRANSITION METAL ALLOY CATALYSTS

摘要

Provided is a catalytically active particle comprising an alloy, said alloy comprising: greater than or equal to 50 atomic % ruthenium (Ru); and 1 to 50 atomic % of one or more transition metals (M) selected from cobalt (Co), nickel (Ni), and iron (Fe), wherein the sum of the atomic percentages of Ru and M is greater than 65 atomic % of the alloy, and wherein, in the particle, the alloy is not fully or partially encapsulated by a layer of platinum atoms. Devices and processes employing the catalytically active particle are also provided.
