摘要
A process of doping zero-valance double metals into a cationic exchange resin to increase reactive activity of zero-valance metals includes providing a cationic exchange resin to contact a first metal in the form of ions to reduce the first metal which then attaches to the cationic exchange resin; providing a second metal in the form of ions to contact and attach to the first metal; and reducing the second metal to zero valance and forming a carrier containing double metals. The cationic exchange resin is selected from a strong acidic ion exchange resin of which the ion exchange functional group is SO3Na and SO3H. The first metal is selected from the noble metal group: palladium, platinum and copper. The second metal is selected from the normal metals group, such as tin. The first metal and the second metal respectively have particle diameters ranging from 20 to 100 nm.
