氮掺杂稻壳基多孔炭的制备及其氧气还原反应的电催化性能(英文)
发布时间:2021-02-02 22:04
本文发展了一种氮掺杂稻壳基多孔炭(N-RHPC)的制备方法,即将RHPC在氨气氛围下进行高温处理,操作简单,有利于大规模制备。结果表明,N-RHPC的介孔体积、石墨化程度明显提高,XPS N 1s谱证实了N原子在RHPC结构上的有效掺杂。N-RHPC作为ORR电催化剂具有与商用Pt/C接近的电催化活性,并具有较好的稳定性以及耐甲醇毒性,这主要是由于氨气氛围下对RHPC的高温处理使N原子进入RHPC中而引入了大量的催化位点所致。N-RHPC制备方法简单,性价比高,作为电催化剂具有很好的应用前景。
