| 摘 要： | 将桉树叶提取液绿色还原氧化石墨烯(G-rGO)电极和微生物还原氧化石墨烯(B-rGO)电极依次作为微生物燃料电池(MFC)阳极,采用红外光谱(FTIR)、X射线衍射(XRD)、扫描电镜(SEM)对所制备的电极进行表征,并采用循环伏安法(CV)、交流阻抗法(EIS)对比2种电极的电化学性能.结果发现,G-rGO阳极的内阻为243.87Ω,应用于MFC时最大功率密度和最大输出电压分别为18.77 W·m~(-3)和760 mV,对照组B-rGO电极的内阻为299.11Ω,将其应用于MFC时最大功率密度和最大输出电压分别为13.16 W·m~(-3)和635 mV,对照组未修饰阳极的内阻为375.21Ω,最大功率密度和最大输出电压分别为8.97 W·m~(-3)和480 mV.研究表明,G-rGO电极电阻更小,导电性能更优越.

| Abstract: | Green-reduced graphene oxide (G-rGO) film electrode and bio-reduced graphene oxide (B-rGO) film electrode are used as anodes in microbial fuel cells (MFCs) to examine their performance in electricity generation. The anodes were characterized by fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscope (SEM). Furthermore, the electrochemical techniques such as cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) were applied to explore the electrochemical performance. The internal resistances of G-rGO group was 243.87 Ω with the maximum power densities and output voltage at 18.77 W·m-3 and 760 mV, respectively. However, the internal resistances of unmodified group and B-rGO group were larger at 375.21 Ω and 299.11 Ω. Besides, lower power density and output voltage were shown at 8.97 W·m-3 and 480 mV for control group and 13.16 W·m-3 and 635 mV for B-rGO group. Above all, it demonstrates that G-rGO film anodes performed better and can be applied as anode materials in MFC to accelerate electricity generation. |
