An Efficient Electrocatalyst (PtCo/C) for the Oxygen Reduction Reaction

The oxygen reduction reaction (ORR) is paid much more attention because of the high overpotential required for driving four-electron process in field storage and sustainable energy conversion, including fuel cell applications. In this paper, PtCo nanoparticles encapsulated on carbon supports were prepared by a simple modified polyol method with ethylene glycol. Structural as well electrochemical characterizations illustrated that PtCo/C electrocatalysts had minimum particle size 4.8 nm, which close to commercial 40 wt% Pt/JM. Moreover, measurements indicated ORR activity was competitive Pt/JM catalyst. synthesis critical way produce catalysts use polymer electrolyte membranes cells (PEMFCs).
