Abstract：
 A catalyst with high reaction activity, selectivity and stability for preparing halophenylamine by catalytic hydrogenation of halonitrobenzene is composed of carrier (ZrO2, TiO2, SiO3, or MgO) and active component (Au) (0.5-10 Wt %). Its preparing process includes such steps as providing chloroauric acid as precursor, depositing with urea, and ageing, washing, drying, and calcining at 200-350 deg.C.
