Au/γ-Fe₂O₃,Au/α-Fe₂O₃ and Au/Fe₃O₄ catalysts were prepared via deposition-precipitation methods and characterized by X-ray diffraction.The catalytic performance of these catalysts was studied and compared for the hydrogenation of 3-nitrostyrene.In addition,the influences of temperature,support as well as the reaction medium were discussed.The results showed that the conversion of 3-nitrostyrene in H₂O is much higher than that in ethanol and solvent-free system,and it increased with increasing of temperature,however,the selectivity to 3-aminostyrene did not change.The catalytic activity of Au/FeO_x catalysts was in an order of Au/γ-Fe₂O₃ >Au/α-Fe₂O₃ >Au/Fe₃O₄.The different reducibility of the iron oxide supports may be the main reason for such a catalytic activity.
