摘要:采用硬模板法,使用价格低廉的间苯二酚作为炭前驱体,采用氟化铵作为氟氮来源,合成氟氮掺杂的有序介孔碳(F-N-OMC)。在1 000℃时制备的氟氮掺杂的有序介孔碳材料中,大量的氟氮原子(F原子数分数为0.35%,N为2.25%)均匀注入到高表面积的石墨化碳基体(671.3cm^2/g)和有序介孔通道内(6.2nm)。碳骨架内的氟氮原子的合成效果可以显著地极化相邻碳原子,并推动由缺陷引发的氧还原反应活性部位的形成。这将有助于氧还原反应性能的提高,因此氟氮掺杂的介孔碳材料有望成为高效的氧还原反应催化剂。
By adopting a hard template method,the ordered mesoporous Kong Tan(F-N-OMC)doped with fluorine nitrogen is synthesized by using inexpensive resorcinol as carbon precursor and ammonium fluoride as a fluorine and nitrogen source.Considerable fluorine and nitrogen atoms(F:0.35at%,N:2.25at%)are homogeneously implanted in the graphitic carbon matrix with high surface area(671.3cm^2/g)and ordered mesoporous channels(6.2nm)of FN-OMC prepared at the optimized heat-treatment temperature of 1 000℃.The synergistic effect of fluorine and nitrogen atoms in carbon frameworks is demonstrated to sharply polarize adjacent carbon atoms and promote the formation of the active sites of oxygen reduction reactions induced by defects.This will help to improve the performance of oxygen reduction reaction.Therefore,the FN-OMC is expected to become an efficient catalyst for oxygen reduction reaction.
