氮摻雜稻殼基多孔炭的制備及其氧氣還原反應的電催化性能(英文)
發(fā)布時間:2021-02-02 22:04
本文發(fā)展了一種氮摻雜稻殼基多孔炭(N-RHPC)的制備方法,即將RHPC在氨氣氛圍下進行高溫處理,操作簡單,有利于大規(guī)模制備。結果表明,N-RHPC的介孔體積、石墨化程度明顯提高,XPS N 1s譜證實了N原子在RHPC結構上的有效摻雜。N-RHPC作為ORR電催化劑具有與商用Pt/C接近的電催化活性,并具有較好的穩(wěn)定性以及耐甲醇毒性,這主要是由于氨氣氛圍下對RHPC的高溫處理使N原子進入RHPC中而引入了大量的催化位點所致。N-RHPC制備方法簡單,性價比高,作為電催化劑具有很好的應用前景。
