palladium catalyst

 Among precious metal catalysts, palladium catalysts are the most commonly used. Palladium catalysts are widely used in hydrogenation, dehydrogenation, and oxidation reactions, especially in the purification and treatment of organic exhaust gas VOCs in chemical, paint, enameled wire, coating, oven and other industries. It can also be used in the hydrogenation reaction of olefins and aromatic nitro compounds, and can also be applied to dehalogenation and carbonylation. Compared with Raney nickel catalysts, palladium catalysts can react at low temperature and pressure, with less dosage and fewer side reactions.
