以活性炭纤维毡（ ACF）为基体制备出了ACF-OMC、ACF-C-TiO2、ACF-TiO23种活性炭纤维复合材料，作为电芬顿反应的充氧阴极．采用扫描电子显微镜（ SEM）、透射电子显微镜（ TEM）、X射线粉末衍射仪（ XRD）、N2物理吸附-脱附对材料进行了表征，以苯酚模拟特征污染物，对3种复合材料的电芬顿性能进行了比较研究．高效液相色谱（ HPLC）检测结果表明：3种活性炭纤维复合阴极材料均显著提高了对污染物的降解效果；苯酚降解的准一级速率常数依次为：ACF-OMC＞ACF-C-TiO2＞ACF-TiO2＞ACF．液质联用（ LC-MS）显示：电芬顿降解苯酚的主要中间产物为苯醌和邻苯二酚，ACF-OMC充氧阴极对中间产物同样表现出最高的降解能力．

Three composite activated carbon fiber(ACF) cathodes, ACF-OMC(ordered mesoporous carbon), ACF-C-TiO2 , and ACF-TiO2 were successfully synthesized, which were employed as oxygenation cathode in electro-Fenton system. After being characterized by SEM, TEM, XRD and N2 Adsorption-Desorption, the electro-Fenton performance of three composite were comparatively investigated with phenol as simulated pollutant.HPLC detection showed that all the three ACF composites could improve the degradation of pollutants effetively, and the pseudo-first-order degradation rate constants for phenol were in the order:ACF-OMC>ACF-C-TiO2 >ACF-TiO2 >ACF.Furthermore, LC-MS detection proved that the main intermediate products of phenol were benzoquinone and catechol, which were also degraded fastest by the ACF-OMC oxygenation cathode.
