摘要：

Ammonia treatment of ordered mesoporous carbons at high temperature results in the formation of nitrogen-doped carbon materials that exhibit significant activity for oxygen reduction reaction in acidic media. The new material shows an onset potential of only 80 mV below that of a commercial Pt-based catalyst, but a better stability. © 2010 American Chemical Society.
