Widely used as a heterogeneous catalyst in organic synthesis, particularly in hydrogenation and dehydrogenation reactions. It facilitates the addition of hydrogen to alkenes, alkynes, nitriles, and aromatic compounds under mild conditions. Commonly employed in pharmaceutical manufacturing for selective reduction steps due to its stability and reusability. Also applied in fine chemical production and petrochemical processes where efficient catalyst recovery is essential. Its support on alumina enhances dispersion and thermal stability, making it suitable for both batch and continuous flow systems. Additionally used in environmental applications such as catalytic converters and hydrogen purification systems.
