Abstract: A novel ion-exchange resin supported amorphous Ni-B alloy catalyst was prepared. Three kinds of resins were used as supporter: weakly acidic cation exchanger D152, strong acidic cation exchanger D72 and strong basic anion exchanger D261. XPS, TEM and ICP were used to characterize the catalysts. The results showed that the nickel on the catalysts has a strong interaction with the support resins and the interaction varies with the functional group of the resin. Catalyst Ni-B/D261 gave the most oxide peak of Ni 2p_3/2 level in XPS spectrum and catalyst Ni-B/D152 the least. The activity experiments of the liquid phase dehydrogenation of 2-propanol confirmed the results.
