Advanced electrocatalysts for oxygen reduction reaction

摘要

Provided are nanocomposites including an iron-based core and a nitrogen-doped graphitic carbon shell, and methods of making and using the same. Included in the nanocomposites is an Fe₃C-based interlayer between the core and the shell. The nanocomposites can show a catalytic activity toward reducing oxygen comparable to commercial Pt/C catalysts.
