英文摘要	Iron nanoparticles wrapped in N-doped carbon (INC) were synthesized by a two-step method which includes a hydrothermal and a thermal treatment. The PtSn nanoparticles were then deposited on the resulting carbon material using an ethylene glycol reduction method. Scanning electron microscopy images indicated INC had an interconnected, porous framework with continuous macropores in the micrometer range. Transmission electronic microscopy and X-ray diffraction results proved that the iron nanoparticles were completely wrapped in the N-doped carbon. Cyclic voltammograms for ethanol oxidation showed that the mass activity on PtSn/INC electrode reaches 424.5 mA mg(-1) (Pt), 1.64 times as large as that for PtSn/C (259.0 mA mg(-1) (Pt)). PtSn/INC also exhibited better durability in ethanol oxidation reaction than PtSn/C. These results indicated that INC is a potential high-performance catalyst support material for fuel cell catalysts.
