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 electrochemica...

Oxygen reduction reaction (ORR) is the key for development of clean and sustainable fuel cells. However, ORR sluggish kinetics, thereby it remains a grand challenge to develop high-activity, low-cost, long-durability electrocatalysts facilitate process practical application. The introduction dopants into/on carbon skeleton known as an efficient route obtain novel metal-free electrocatalyst ORR....
