    Abstract: The present invention relates to a hydrogenation catalyst for nitro-aromatic compounds, especially nitrobenzene and a method for preparing the same. Particularly, the present invention relates to a hydrogenation catalyst for nitrobenzene, which contains palladium and zinc on a carrier, and is prepared by a process comprising steps of: fixing a zinc component on a carrier; and fixing a palladium component on the carrier on which the zinc component is fixed. Further, it is applicable for a corresponding process for preparing aromatic amino compounds by way of a reaction for hydrogenating nitro-aromatic compounds, and demonstrates improved selectivity, reactivity and stability.
