摘要： Techniques herein prepare an alloy catalyst using a protective conductive polymer coating. More particularly, an alloy catalyst is prepared by: preparing a platinum catalyst supported on carbon; coating the surface of the platinum catalyst with a conductive polymer; supporting a transition metal salt on the coated catalyst; and heat treating the catalyst on which the transition metal salt is supported. Also, an alloy catalyst may be prepared by: preparing a platinum-transition metal catalyst supported on carbon; coating the surface of the platinum-transition metal catalyst with a conductive polymer; and heat treating the coated catalyst. Accordingly an alloy catalyst with superior dispersity can be prepared by increasing the degree of alloying of the catalyst through heat treatment while preventing the increase of catalyst particle size through carbonization of the conductive polymer. The prepared catalyst may be useful, for example, for a fuel cell electrode.
