Palladium on activated charcoal is widely used as a catalyst in various chemical reactions, particularly in hydrogenation and dehydrogenation processes. It plays a crucial role in the pharmaceutical industry for synthesizing active pharmaceutical ingredients (APIs) by facilitating the reduction of nitro compounds, alkenes, and alkynes. In the petrochemical sector, it is employed in refining processes to remove impurities and improve fuel quality. Additionally, it is utilized in organic synthesis for coupling reactions, such as the Suzuki and Heck reactions, which are essential for creating complex organic molecules. Its high efficiency and selectivity make it a preferred choice in both industrial and laboratory settings.
