PROBLEM TO BE SOLVED: To produce a core-shell catalyst having high platinum mass activity in a short time.SOLUTION: A method for producing a core-shell catalyst which comprises a core containing palladium and a shell containing platinum and covering the core includes: preparing a copper-coated palladium-containing particle dispersion liquid in which copper-coated palladium-containing particles obtained by coating the surface of palladium-containing particles with copper are dispersed, a platinum ion-containing solution, and a microreactor; and mixing the copper-coated palladium-containing particle dispersion liquid and the platinum ion-containing solution in the microreactor, thereby substituting copper on the surface of the copper-coated palladium-containing particles with platinum to form the shell.SELECTED DRAWING: Figure 2 |
