| 英文摘要 | The development of low-cost, efficient and stable electrocatalysts for the oxygen reduction reaction (orr) is desirable but remains a great challenge. we report a self-sacrificial template synthesis approach for nitrogen-doped hollow carbon microtubes as electrocatalyst for orr. typically, fe-mil (materiaux de l'institute lavosier) nanocrystals cast as self-sacrificial template. polyaniline (pani) was in situ-synthesized and deposited on the surface of fe-mil nanocrystals. by a two-step pyrolysis of the mil-101 (fe)@pani hybrids, unique microstructured carbon tubes with fe3o4 nanoparticles encapsulated inside the wall were fabricated after the self-sacrificial template decomposed. the optimized c-pani-mil-2 catalyst exhibits a high onset potential of 1.0 v in alkaline media. out of the negative effect of the disruption of metal-organic frameworks (mof) morphology, the ingenious catalytic activities may be ascribed to the well-defined microtube architecture with a high accessible surface area, the existence of fen2+2/fen4 and rich active nitrogen atoms. moreover, c-pani-mil-2 exhibited excellent methanol tolerance and durability compared to a commercial pt/c catalyst in both electrolytes. this work may provide a new strategy for the design and preparation of microstructured non-precious metal based catalysts supported on hollow carbon tubes for fuel cells. |
