英文摘要Fluorine and nitrogen co-doped ordered mesoporous carbon (FN-OMC) is synthesized by a hard template method employing inexpensive resorcin as a carbon precursor and ammonium fluoride as a fluorine and nitrogen source. Considerable fluorine and nitrogen atoms (F: 0.35 at%, N: 2.25 at%) are homogeneously implanted in the graphitic carbon matrix with high surface area (671.3 cm(2) g(-1)) and ordered mesoporous channels (6.2 nm). The FN-OMC prepared at the optimized heat-treatment temperature (1000 degrees C) exhibits a high catalytic activity (E-onset: -0.07 V, E-1/2: -0.19 V, current density: 5.83 mA cm(-2)) for oxygen reduction reaction (ORR) comparable to commercial platinum-carbon (Pt-C, 20 wt%) catalysts, but better stability and methanol-tolerance in alkaline solutions. The synergistic effect of fluorine and nitrogen atoms in carbon frameworks is demonstrated to sharply polarize adjacent carbon atoms and facilitate the formation of defect-induced active sites for ORR.; Shanghai construction of college experiment technique team plan [YJ0114204]; SCI(E); EI; ARTICLE; wanghaiwen0707@163.com; 83; 79928-79933; 6
