What are the Applications of Platinum Alloys in Catalysis?
Platinum alloys are used in various catalytic processes, including:
1. Automotive Catalysts: Platinum-rhodium and platinum-palladium alloys are used in catalytic converters to reduce harmful emissions from vehicle exhausts. 2. Fuel Cells: Platinum alloys, particularly platinum-ruthenium, are employed in proton exchange membrane (PEM) fuel cells to enhance the efficiency of hydrogen oxidation and oxygen reduction reactions. 3. Chemical Synthesis: They are used in the petrochemical industry for processes such as hydrogenation and dehydrogenation. 4. Electrochemical Reactions: Platinum alloys find applications in electrolysis and other electrochemical processes due to their excellent conductivity and stability.
