NOVELTY - A multi-walled carbon nanotube-containing core-shell silver-platinum catalyst comprises multi-walled carbon nanotube carrier and active metal component provided on the surface of the multi-walled carbon nanotube carrier. The active metal component has core-shell structure comprising silver as core material, and platinum as shell material.    USE - Multi-walled carbon nanotube-containing core-shell silver-platinum catalyst is used in fuel cell.    ADVANTAGE - The multi-walled carbon nanotube-containing core-shell silver-platinum catalyst has excellent catalytic activity, and oxidation-reduction in fuel cell.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of multi-walled carbon nanotube-containing core-shell silver-platinum catalyst. A soluble silver salt is dissolved in a mixed liquid containing ethanol and deionized water, such that the concentration of silver ion in the solution is 0.0005-0.01 mol/L, citric acid or citrate and multi-walled carbon nanotube carrier are added sequentially, mixed and uniformly stirred, to obtain mixed solution. Sodium borohydride is dissolved in ethanol solution having concentration of 50-200 mmol/L, and added with the mixed solution in which the content of silver ion and sodium borohydride is 5-10:1 at 50-80 degrees C for 2-6 hours, the resulting reaction solution is cooled, and vacuum dried, to obtain multi-walled carbon nanotube-containing silver-platinum particles. The obtained multi-walled carbon nanotube-containing silver-platinum particles are uniformly dispersed in ethylene glycol solution, and then 0.01-0.02 mol/L of chloromolybdate aqueous solution is added in which the mass ratio of silver and platinum ion in the solution is 0.2-3:1, and sodium hydroxide or potassium hydroxide is added to adjusted the pH value of 7-9, and temperature is maintained at 70-110 degrees C for 2-6 hours, to obtain dispersed reaction solution. The obtained dispersed reaction liquid is centrifugally washed until free from chlorine ion, and dried at 50-80 degrees C, to obtain multi-walled carbon nanotube-containing silver-platinum catalyst. The mass ratio of multi-walled carbon nanotube carrier and silver ion in the solution is 4-25:1. The mass ratio of citric acid or citrate, and silver ion in the solution is 1-2:1.
