AbstractAmmonium ferric citrate (AFC) was used as a single-source molecular precursor to prepare Fe/Fe3C nanoparticles encapsulated in nitrogen-doped carbon by pyrolysis in Ar atmosphere followed by acid-leaching. Comparative studies, using citric acid and ferric citrate as the precursors, indicated that the ammonia and ferric ion in AFC and the pyrolysis temperature affected the composition of iron species and the properties of carbon in AFC-derived materials. Above the pyrolysis temperature of 600 degrees C, the iron species were Fe/Fe3C, and the carbon had a hollow graphitic nanoshell structure in AFC-derived materials. The specific surface area and content of nitrogen element decreased with increasing pyrolysis temperature. The AFC-derived material pyrolyzed at 600 C had the optimal graphitization degree, specific surface area (489 m(2) g(-1)) and content of nitrogen (1.8 wt.%), thus resulted in the greatest activity for oxygen reduction reaction among the AFC-derived materials pyrolyzed at different temperatures. The AFC-derived material pyrolyzed at 600 degrees C exhibited improved methanol-resistance ability compared with Pt/C catalyst. (C) 2014 Elsevier Ltd. All rights reserved.
