| 摘要: 以双金属化合物{[Co （bpy）2]3[Fe （CN）6]2}[Fe （CN）6]1/3为前驱体，采用纳米灌注法制备了具有Fe—N、Co—N和Fe—C≡N—Co活性结构的Fe、Co、N掺杂介孔Fe-Co-N-GC催化剂。Fe-Co-N-GC具有较高的比表面积和石墨化程度，使其氧还原反应（ORR）催化性能显著提高。Fe-Co-N-GC催化剂在ORR过程中表现出优异的稳定性和抗甲醇性能。 |

| Abstract: Using special compound {[Co(bpy)2]3[Fe(CN)6]2}[Fe(CN)6]1/3 as a precursor, an ordered mesoporous Fe-CoN-doped graphite-based catalyst (Fe-Co-N-GC) with the embedding Fe-N, Co-N, and Fe-C≡N-Co active sites was prepared by a nano-casting technique. Together with the high surface area and graphitization degree, the catalytic performance of Fe-Co-N-GC for oxygen reduction reaction (ORR) was remarkably enhanced. This Fe-Cobased bimetallic catalyst also exhibited superior durability and good tolerance to methanol in ORR. |
