Abstract

A method of producing a catalyst including a platinum-transition metal alloy on carbon, more specifically, a method of producing a carbon supported platinum alloy catalyst with high activity and superior durability includes coating a carbon-supported catalyst with an organic polymer as a material for a carbon layer, heat-treating the catalyst under a hydrogen-deficient atmosphere to convert the organic polymer into the carbon layer to prevent growth of catalyst particles caused by heat treatment through the carbon layer, allowing, at the same time, a transition metal supported together with platinum to be diffused into platinum particles to form a catalyst having a core-shell structure including a platinum skin layer on a surface thereof, and removing the carbon layer by ozone treatment after the heat treatment to induce an electrochemical reaction on the surface of the catalyst.
