研究了碳纳米管（CNTs）修饰的静电纺丝活性炭纤维（ACF）（e-CNT/ACF）对甲基橙子（MO）染料的电化学降解。网状碳纳米管/活性碳纤维复合材料中的碳纳米管有助于改善复合材料的孔分布和导电性。以碳纳米管/活性碳纤维网为电极，在60 min内可降解约90%的MO，远高于同等条件下的商用机织活性碳纤维。详细讨论了电解电位、pH值和电解质浓度对MO降解的影响。结果表明，电催化剂对有机物的降解效率与电位和电解质浓度呈线性关系，而pH值对有机物的降解效率有一个最佳值3.0。
The electrochemical degradation of methyl orange (MO) dye over the electrospun activated carbon fiber (ACF) webs modified with carbon nanotubes (CNTs) (e-CNT/ACF) has been studied. The CNTs in the web-likee-CNT/ACF composites help to improve the pore distribution and conductivity of the concerned composites. Withe-CNT/ACF webs as electrodes, about 90% of the MO can be degraded in 60 min, which is much higher than the commercial woven ACF under the similar conditions. The effects of the electrolysis potential, pH and electrolyte concentration on the MO degradation have been addressed in detail. The results show that the MO degradation efficiency over thee-CNT/ACF webs is related linearly to the potential and the electrolyte concentration, while for the pH, it goes through an optimum value of 3.0.
