DESCRIPTION:

Title: Synthetic and processing of carbon-supported monometallic, Binary and Ternary Metal Nanoparticles a fuel cell catalysts. 

Abstract:  This invention describes a new technology that allows controllable preparation of highly active carbon-supported monometallic, binary and ternary nanoparticles as fuel cell catalysts.  The working principles of the preparation involve core-shell approach in nanoparticle synthesis, controlled assembly and controlled calcination.  The immediate application of this technology is fuel cell catalysis technology.  In addition, it may find a wide range of applications involving the use of metal catalysts.

ADVANTAGES:

In comparison with existing methods for catalyst preparation (e.g. co-precipitation, impregnation, etc.) this new technology offers advantages in a number of areas.  First, the size is fully controllable in the 2nm range with highly monodispersity.  Secondly, the monometallic, binary and ternary compositions are fully controllable.  Thirdly, the nanoparticles are assembled onto carbon support with controllable loading.  Fourthly the carbon-supported nanoperticle catalysts can controllably calcinated with desired sizes and compositions.  Finally, the calcinated carbon-supported catalysts exhibited electrocatalytic activities higher than existing commercial catalysts.
