Abstract: Disclosed herein is a method of preparing an alloy catalyst for fuel cells, which is suitable for mass production and can reduce manufacturing costs. The method includes vaporizing at least two catalyst precursors in separate vaporizers; supplying the at least two vaporized catalyst precursors to a reactor while preventing contact therebetween; and synthesizing an alloy catalyst in the reactor. The method can prepare an alloy catalyst through a one-step process unlike typical multi-step methods for preparing catalysts, and can prepare an alloy catalyst at a much lower temperature than the typical methods for preparing alloys, thereby enabling mass production and cost reduction.

Abstract: A method of preparing a metal-carbon composite of a core-shell structure through simultaneous vaporization, in which a metal particle constitutes a core and carbon constitutes a shell, with the metal-carbon composite prepared in the form of powder and supported on a supporter, and a metal-carbon composite of a core-shell structure prepared by the same. In these methods, the metal-carbon composite of the core-shell structure is prepared through simultaneous vaporization of metal and carbon precursors and does not require separate post-processing. Further, in the metal-carbon composite of the core-shell structure prepared by these methods, a carbon shell covers a portion or the entirety of a surface of a metal core, whereby the metal particles can be prevented from suffering agglomeration, separation or corrosion when subjected to harsh process conditions at high temperatures for long durations under strong acid and alkali conditions, thereby providing high performance and high durability.
