通过恒电流法电沉积分别制备了氧化石墨烯/聚吡咯(GO/PPy)复合材料修饰碳毡(CF)阳极和还原氧化石墨烯/聚吡咯(r GO/PPy)复合材料修饰碳毡阳极.通过循环伏安法和交流阻抗法对电极特性进行考察.将其分别应用到微生物燃料电池中,对其产电性能进行研究.结果表明,相比r GO/PPy-CF电极,氧化石墨烯以掺杂方式加入到聚吡咯中,一步电聚合制备的GO/PPy-CF电极,其电极性能更为优异,且作为MFC阳极时,对电池的产电性能提升更大.该电极制备方法简单,无需使用强还原剂,是一种有效环保的MFC阳极制备方法.
The GO / PPy composite modified carbon felt (CF) anode and the GO / PPy composite modified carbon felt anode were prepared by galvanostatic electrodeposition. The characteristics of the electrodes were investigated by cyclic voltammetry and AC impedance spectroscopy, respectively, and applied to microbial fuel cells to study their electricity production performance. The results showed that compared with r GO / PPy-CF electrodes, graphene oxide The electrode performance of the GO / PPy-CF electrode prepared by one-step electropolymerization is more excellent when the doping method is added to the polypyrrole, and the production performance of the battery is greatly improved when used as the MFC anode. The preparation method of the electrode is simple, Without the use of strong reductant, it is an effective and environmentally friendly MFC anode preparation method.
