活性炭改性后的實際應用
文章作者:博猫娱乐注册網絡部 更新時間:2019-2-25 11:52:01

  為了探索活性炭化學表面改性引起的效應,研究人員已經在各種實際應用中開發了改性活性炭(表1)。本期介紹活性炭的一些應用領域。

  BIAO1:HUOXINGTANDEJIZHONGGAIXINGFANGFA。

原材料

活化方法

改性后的變化

活性炭

KOH活化

增加表面積導致高比電容

活性炭

2%重量的六胺進行氮摻雜

增加了超級電容器應用的電極電容

活性炭

硝酸氧化

在氧化后增強了能量密度

活性炭

木質材料H 3 PO 4制備活性炭,并用NH 3改性

加入氮基團增了的吸附速度和容量

活性炭

通過酸和堿處理產生高極性碳表面

對相對極性的甲基叔丁基醚和相對非極性的三氯乙烯吸附

活性炭

HNO 3HCl 酸處理

酸處理產生更多活性的酸性表面基團,例如羧基和內酯,導致堿性染料的吸附減少

活性炭

使用HNO 3H 2 O 2NH 3進行化學處理

由于活性炭的化學改性,具有優異的染料吸附性能

  活性炭作為超級電容器
