The present invention provides a method for preparing a core-shell particle supported with a carrier, and a core-shell particle prepared thereby, the method comprising the steps of: forming a solution by adding to a solvent a first metal which is supported with the carrier; adjusting the pH of the solution to 7 to 14, and adding a metal salt of a second metal; and forming the core-shell particle by adding a reducing agent to the solution, and forming a shell comprising the second metal on the surface of a core particle comprising the first metal. |
