Monodisperse Pt{sub 3}Co nanoparticles as a catalyst for the oxygen reduction reaction : size-dependent activity.
Monodisperse Pt{sub 3}Co nanoparticles with size controlled from 3 to 9 nm have been synthesized through an organic solvothermal approach and applied as electrocatalysts for the oxygen reduction reaction. Electrochemical study shows that the Pt{sub 3}Co nanoparticles are highly active for the oxygen reduction reaction and the activity is size-dependent. The optimal size for maximal mass activity was established to be around 4.5 nm by balancing the electrochemically active surface area and specific activity.
