聚丙烯腈基活性炭纤维（ＰＡＮ－ＡＣＦ）对硫化氢（Ｈ_２Ｓ）有比其他活性炭材料更强的吸附能力。Ｈ_Ｓ在ＰＡＮ－ＡＣＦ上的吸附是一个兼具物理吸附特征的化学吸附、催化转化过程。其化学吸附位主要位于微孔表面。吸附过程为：Ｈ_２Ｓ分子首先被物理吸附进入微孔空间，而后在微孔表面的化学吸附位上进行包含电子转移的化学吸附、催化氧化，在炭表面产生相对稳定的化学结构。
Polyacrylonitrile-based activated carbon fiber (PAN-ACF) hydrogen sulfide (H_2S) has more adsorption capacity than other activated carbon materials. The adsorption of H_S on PAN-ACF is a chemisorption that combines both physical adsorption and catalytic properties. The chemical adsorption site is mainly located in the microporous surface. The adsorption process is as follows: H 2 S molecules are first physically adsorbed into the micropore space, and then chemical adsorption including electron transfer is performed on the chemisorption sites on the micropore surface to catalyze oxidation to produce a relatively stable chemical structure on the carbon surface.
