Widely used as a heterogeneous catalyst in organic synthesis, particularly in hydrogenation and dehydrogenation reactions. It is effective in reducing alkenes, alkynes, nitro groups, and carbonyls under mild conditions. Commonly employed in pharmaceutical manufacturing for selective hydrogenation steps due to its high activity and ease of separation from reaction mixtures. Also used in coupling reactions such as Suzuki, Heck, and Sonogashira, where it facilitates carbon-carbon bond formation. Its support on activated carbon provides a high surface area and enhances stability and reusability. Applied in fine chemical production and in the synthesis of agrochemicals, flavors, and fragrances. Additionally, used in industrial processes for purifying gases and removing trace oxygen or hydrogen from closed environments.
