摘要

微生物燃料电池（MFC）是一种利用微生物将有机物中的化学能直接转化成电能的装置，通过改善阳极特性可以有效提高微生物燃料电池的产电性能。通过恒电流法电沉积制备了氧化石墨烯/聚3

4-乙烯二氧噻吩（GO/PEDOT）复合材料修饰碳毡（CF）阳极。通过循环伏安法和交流阻抗法考察了电极特性。将其应用到微生物燃料电池中，对其产电性能进行评价。结果表明，GO/PEDOT-CF电极具有较大的比表面积和优良的电化学性能；以GO/PEDOT-CF为阳极的微生物燃料电池，产电性能良好，其最大功率密度和最大电流密度达到1.138 W·m-2和4.714 A·m-2，分别是未修饰阳极的4.80倍和5.51倍。因此，GO/PEDOT复合材料是一种优良的阳极修饰材料，可有效提高MFC的产电性能。

Abstract

A microbial fuel cell (MFC) is an innovative power output device. The properties of the anode is a critical factor for improving the performance of MFC. In this study

a graphene oxide/poly(3

4-ethylenedioxythiophene) (GO/PEDOT) composite was prepared and used for modification of carbon felt (CF) via the electrodeposition with constant current. The cyclic voltammetry and electrochemical impedance characteristics of the electrode were evaluated. Furthermore

the as-prepared anode was applied in MFC and its electrogenesis capacity was investigated. The results showed that the GO/PEDOT-CF electrode had a large specific surface area and good electrochemical performance. When the GO/PEDOT-CF anode was used in MFC

the maximum power density and current density were up to 1.138 W·m-2 and 4.714 A·m-2

respectively

which were 4.80 times and 5.51 times higher than those of unmodified anodes. These results demonstrated that the GO/PEDOT composite is a kind of effective anode materials for improving electricity generation of MFC.
