Abstract
Nanostructured graphitic carbon materials have wide applications. However, the synthesis of such materials with a high surface area is still a great challenge. In this study, graphitic carbon nanocages with a surface area as high as 400–800 m2 g−1 were synthesized by pyrolysis of ethanol with dissolved iron carbonyl. This graphitic carbon was successfully applied as an electrode material for proton exchange membrane fuel cells and showed 40% improvement in fuel cell performance from amorphous carbon. The present method could be applied to large-scale production of graphitic carbon with a high surface area and would be practically relevant for fuel cell and many other technologies.
