Gold-Based Alloy Nanoparticles for Use as Fuel Cell Catalysts

A synthesis method specifically for alloy nanoparticles comprising Pt and Co raining in diameter from 1-5 nm 

 Technology Overview:  

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.
