Abstract：
 A preparation method for a catalyst used for catalytic decomposition of hydrogeniodide belongs to the catalyst preparation technical field. A method of immersion is first adopted by the present invention. A carrier is immersed in a dissolvable salt comprising a noble metal used for activation or a soluble acid water solution, and then dried to get an activated precursor. The mass of the noble metal for activation is 0.1 to 5 percent of the mass of the carrier. The activated precursor is added into a reducer solution to manufacture an activated substrate by reducing. Finally, the activated substrate is put in a chemical platinum plating solution to realize oriented deposition of activated platinum metal on the carrier. Thus, the catalyst for decomposition of hydrogeniodide is manufactured. The mass content of platinum in the catalyst is 1 to 50 percent. The catalyst preparation method is provided with the advantage of the good repeatability for mass production, the good platinum dispersion and the high catalytic activity. The catalyst manufactured with the method is not only applicable for the catalytic decomposing reaction of hydrogeniodide, but also can be used as the catalyst for the catalytic hydrogenation reaction.
