Abstract

We propose a new chemical route for forming ultramicropores in carbon nanofibers by using a pore former, camphor, in electrospun polyacrilnitrile nanofibers. The resulting carbon nanofibers form mostly ultramicropores. Total specific surface area was 886 m(2) g(-1), which is similar to the activated carbon nanofibers in CO(2) and steam activation.

摘要

我们提出了一种新的化学途径，通过在电纺聚丙烯腈纳米纤维中使用造孔剂樟脑来形成碳纤维纳米纤维中的超微孔。所得到的碳纤维纳米纤维主要形成超微孔。总比表面积为 886 m(2) g(-1)，与 CO(2)和水蒸气活化的活性炭纳米纤维相似。
