摘要
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.
Microbial fuel cell （MFC） is a kind of bioelectrochemical system that extracts electric energy from the organic compounds available in wastewaters by micro-organism. Enhancing the anode properties, including high conductivity, high specific surface area, high porosity, etc., is a critical step for improving the performance of MFC. A graphene oxide/polypyrrole （GO/PPy） composite anode and a reduced gra- phene oxide/polypyrrole （GO/PPy） composite anode were prepared and used for modification of carbon felt （CF） via constant current electrodeposition respectively. Cyclic voltammetry and electrochemical impedance spectroscopy characteristics of the electrode were studied. The prepared anodes were applied in MFC and its properties were investigated. The results showed that the GO/PPy-CF anode which was prepared by constant current electrodeposition in one step, had better performance as MFC anode as compared to re- duced graphene oxide （rGO）/PPy-CF anode. In addition, the preparation of GO/PPy-CF anode was effective and environmentally-friendly, which was a simple method and no need strong reducing agent.
