- Description
- 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.
