摘要:
Disclosed is a method for preparing nickel or palladium nanoparticles supported on a carbon support. To a mixture solution wherein a stabilizer is dissolved in 1,2-propanediol, a carbon support is added to prepare a dispersion. Then, a precursor solution wherein a nickel or palladium precursor dissolved in 1,2-propanediol is mixed therewith and stirred. Then, nickel or palladium nanoparticles supported on the carbon support are prepared by reduction. The disclosed method for preparing nickel or palladium nanoparticles supported on a carbon support allows preparation of nanoparticles with narrow particle size distribution and good dispersibility through a simple process and the resulting nickel or palladium nanoparticles may be usefully applied, for example, as electrode materials of fuel cells.

摘要:
The present invention features a method for increasing hydrophilic properties of crystalline carbon using a surface modifier and a method for preparing a Pt/C catalyst using the same. In certain preferred embodiments, the present invention features a method for increasing hydrophilic properties of crystalline carbon having water repellency by forming π-π interaction between the surface of the crystalline carbon and a surface modifier and a method for preparing a catalyst by supporting platinum (Pt) on the crystalline carbon having increased hydrophilic property. The Pt/C catalyst prepared by the methods of the present invention is useful for the preparation of electrode materials for fuel cells.
