| 摘 要： | 制备了纳米铁/碳纳米管(Fe/CNTs)复合氧阴电极,通过SEM、EDS、XRD对电极进行了表征。基于该氧阴电极中性条件下电-Fenton降解Rhodamin B(RhB)溶液的试验表明,外加电压1.2 V、通入空气量0.1 m3/h、反应120 min、5mg/L的RhB溶液降解率达到92.1%,说明H2O2和离子态铁可以通过电化学还原在该氧阴极表面高效产生,RhB可通过E-Fenton反应高效去除。

| Abstract: | In this study,a nanoscale iron/carbon nanotube(CNT) composite cathode was synthesized and evaluated by X-ray diffraction(XRD),scanning electron microscopy(SEM),and engery dispersive X-ray spectroscopy(EDX) respectively.It was found that 92.1% degradation of 5 mg/L Rhodamin B(RhB) was achieved in the presence of 1.2V potential and air(0.1m3/h) based on the eletro-Fenton reaction using a nanoscale Fe/CNTs composite cathode at a neutral pH.The results indicated that both H2O2 and iron ions could be effectively generated by electrochemical reduction from Fe/CNTs cathode and RhB could be rapidly eliminated. |
