Sub-50 nm iron-nitrogen-doped hollow carbon sphere-encapsulated iron carbide nanoparticles (Fe<sub>3</sub>C-Fe,N/C) are synthesized by using a triblock copolymer of poly(styrene-<i>b</i>-2-vinylpyridine-<i>b</i>-ethylene oxide) as a soft template. Their typical features, including a large surface area (879.5 m<sup>2</sup> g<sup>-1</sup>), small hollow size (≈16 nm), and nitrogen-doped mesoporous carbon shell, and encapsulated Fe<sub>3</sub>C nanoparticles generate a highly active oxygen reductio ...[more]
