Disclosed is a method for preparing a carbon-supported platinum-transition metal alloy nanoparticle catalyst using a stabilizer. According to the method, the transition metal on the nanoparticle surface and the stabilizer are simultaneously removed by treatment with acetic acid. Therefore, the method enables the preparation of a carbon-supported platinum-transition metal alloy nanoparticle catalyst in a simple and environmentally friendly manner compared to conventional methods. The carbon-supported platinum-transition metal alloy nanoparticle catalyst can be applied as a high-performance, highly durable fuel cell catalyst.
A method for preparing a carbon-supported platinum-transition metal alloy nanoparticle catalyst, comprising (a) mixing a platinum precursor, a transition metal precursor, carbon, a stabilizer, and a reducing agent solution, and washing and drying the mixture to obtain platinum-transition metal alloy nanoparticles supported on the carbon;
