1. Fuel Cells: Platinum alloy catalysts are crucial in the cathodes of proton exchange membrane (PEM) fuel cells, where they facilitate the oxygen reduction reaction. 2. Automotive Catalytic Converters: These catalysts help in reducing harmful emissions by converting toxic gases like carbon monoxide, hydrocarbons, and nitrogen oxides into less harmful substances. 3. Chemical Synthesis: Platinum alloy catalysts are used in numerous industrial processes, including hydrogenation, dehydrogenation, and oxidation reactions.
