摘要

"The palladium based hydrogenation catalysts, platinum or rhodium, on a support of oxides of zircu00c8nio and silu00eccio, processosde manufacture and use of the same, and.The manufacturing process of hydrogen peroxide.Hidrigenau00e7u00e3o catalysts based on palladium, platinum or rhodium, comprising at least one other metal M, deposited on substrates made of oxides of zirconium and silicon.Manufacturing process of these catalysts by impregnation of the support bracket with the help of palladium, platinum or rhodium, and another metal.The use of these catalysts in hydrogenation reactions, especially for preparing hydrogen peroxide.
