1. Automotive Catalysts: Both Pt and Pd are used in automotive catalytic converters to reduce harmful emissions. Pt is particularly effective for oxidizing carbon monoxide (CO) and hydrocarbons, while Pd excels in reducing nitrogen oxides (NOx). 2. Hydrogenation Reactions: Pd catalysts are widely employed in hydrogenation reactions, especially in the pharmaceutical and petrochemical industries. For instance, Pd/C (Palladium on Carbon) is a common catalyst used in the hydrogenation of alkenes to alkanes. 3. Fuel Cells: Pt is a key component in proton exchange membrane (PEM) fuel cells, which are used to generate electricity in a clean and efficient manner.
