GO/PEDOT复合材料修饰阳极的制备及其在MFC中的应用
Preparation and application of GO/PEDOT composite anode for MFC
摘要
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.关键词
