| 简介 |
The present invention provides a method for producing a catalyst in which a porous carrier made of one or more metal oxides or carbon supports thereon catalyst particles comprising one or more precious metals and one or more typical elements or rare earth metal elements or oxides of these elements, the method including the steps of : (1) forming a composite complex in which the precious metal(s) and the typical element(s) or the rare earth metal element(s) are bonded to the polymer compound through coordination bonding, ionic bonding or covalent bonding, the complex comprising 10 to 50000 atoms in total of these elements in one molecule thereof, by reacting a water soluble polymer compound with ions of the precious metal(s) and ions of the typical element(s) or the rare earth metal element(s); (2) supporting the composite complex on the porous carrier; and (3) firing and/or reducing the porous carrier with the composite complex supported thereon. |
