Research Abstract

Precious metals such as Pt have been utilized as catalytically active components for various reactions. However, it is required to reduce the loading of preciousmetals in the catalysts due to their high costs. It has been reported that the alloying of precious metals with transition metals enhances the catalytic activity of the precious metals. However, the preparation of alloy particles with small size is a challenging task, because the preparation of alloys needs the treatment at high temperatures. In the present study, we demonstrated that Pt-based alloy nanoparticles with diameters of a few nanometers can be prepared by using carbon nanofibers as supports. The porous structure of carbon nanofibers prevents the aggregation of the alloy particles at high temperatures.
