Gold-Based Alloy Nanoparticles for Use as Fuel Cell Catalysts

This technology provides a synthesis method specifically for alloy nanoparticles comprising Pt and Co. The method includes reacting a Pt-containing precursor, a Co-containing precursor, at least one capping component, in a solvent system to produce Pt and Co-containing alloy nanoparticles raining in diameter from 1-5 nm. The size of the Pt and Co-containing alloy nanoparticles can be controlled by the ratio of concentration of the capping component to the total concentration of both the Pt-containing and Co-containing precursors.

Advantages:

  • Catalysts display high electrocatalytic activity and stability for oxygen reduction reaction (ORR).  
  • Catalyst cost is reduced by the use of a less expensive non-PGM metal.
