摘要:
Graphene has attracted widely attention due to its good electrical conductivity, high specific surface area and good biocompatibility. The graphene with specific surface area of 535 m2/g was obtained by using chemical reduction method. In the present study, the graphene modified carbon cloth (GNS-anode) was used as a microbial fuel cell anode and compare the perormonce with multi-walled carbon nanotubes modified carbon cloth (MWCNT-anode) and carbon cloth (CC-anode). With GNS-anode, the microbial fuel cell yields a maximum power density of 652 mW/m2, which is 1.4 times and 2.2 times larger than that of the MFC with MWCNT-anode and CC-anode respectively. The great improvement is attributed to the fact that the graphene has high specific surface area, high electrical conductivity and good biocompatibility. The electrodes are characterized by scanning electron microscopy (SEM), Brunauer Emmett Teller (BET), transmission electron microscope (TEM) and X-ray diffraction (XRD). The electrochemical properties have been investigated by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS).
