Tunable nitrogen-doped carbon aerogels as sustainable electrocatalysts in the oxygen reduction reaction, Journal of Materials Chemistry A 1(2013)4002-4009.影響因子:6.626 摘要:A one pot hydrothermal synthesis towards nitrogen doped organic aerogels with tunable surface area and nitrogen content is presented. The gels were synthesized froma sustainable glucose carbon precursor with 2 pyrrol carboxaldehyde (PCA) as the nitrogen source and borax mineral as the structure forming agent. The particle size and hence surface area could be tuned from 75 nm down to 15 nm by varying the amounts of borax added. Similarly, the nitrogen content could be adjusted between 2.0 wt% and 5.5 wt% by varying the amount of PCA added to the glucose solution. Electrochemical testing of the nitrogen doped carbon aerogels as non-metal oxygen reduction catalysts revealed increasing activity with higher surface area and higher nitrogen content, as well as excellent long term stability. Our work thereby demonstrates the high potential of hydrothermal carbon materials and also provides a facile approach toward tunable nitrogen doped aerogels which should be useful for a wide range of applications. 中文翻譯摘要:比表面積和氮含量可調(diào)的氮摻雜的有機氣凝膠用水熱法合成。這種凝膠由連續(xù)的葡萄糖碳前驅(qū)體,氮源PCA和結(jié)構(gòu)形成劑硼砂礦物合成。通過改變硼砂的加入量,顆粒尺寸和表面積可以由75nm調(diào)節(jié)到15nm。類似的,通過改變葡萄糖溶液中PCA的加入量氮的含量可以在2.0wt%和5.5%wt%范圍內(nèi)調(diào)節(jié)。非金屬氧還原催化劑氮摻雜的碳氣凝膠的電化學(xué)測試表明提高了活性,具有高的表面積和高的氮含量和好的長時間的穩(wěn)定性。因此我們的工作表明,水熱法合成的碳材料具有高的電勢,也提供了一種溫和的方法制備可調(diào)的氮摻雜的碳氣凝膠,該方法應(yīng)該被應(yīng)用到更廣泛的領(lǐng)域。 想獲得更多資源可點擊鏈接http://www.tjdrfk.com/news/wdvfrtgcv.html 圖片4.jpg 圖片1.jpg 圖片2.jpg 圖片3.jpg |
