| Abstract: | The supported catalyst P1 was prepared with hydrazine hydrate and potassium borohydride as(co-reducers) in a mixed solvent consisting of methanol,ethanol and water in a proper proportion.The catalyst was a kind of nanosized amorphous alloy characterized by TEM,XRD and SAED.Catalyst P1 was used to(catalyze) the hydrogenation of o-chloronitrobenzene,and compared with the amorphous catalyst P2 prepared by the common method.As it is shown in the results,the activity and selectivity of P1 are slightly higher than those of P2,and the amount of potassium borohydride consumed in the preparation of P1 was only half of that in the preparation of P2.The effects of hydrazine hydrate,potassium borohydride,pH and solvent on the(properties) of the catalyst were also discussed. |
