Microbial fuel cells (MFCs) are devices that can directly convert organic chemical energy into electrical energy with microbial as catalysts. MFCs are a promising bio-electrochemical system with the potential to degrade organic sewage and produce electricity. This article supplies a critical and comprehensive review for the electrode materials concerning about anode and cathode in MFCs, including the fabrications, functional modifications and surface constructions of electrode materials, as well as their applications in MFCs. Additionally, the existing problems of electrode materials in current MFCs have been demonstrated in order to provide the guideline for exploring the next-generation electrode materials for MFCs.

The LiFeSO4F was successfully synthesized from the reactions of FeSO4?xH2O (x=1, 4, 7) with LiF in tetraethylene glycol media through a facile low temperature method. The structures and microscopic features of the products were characterized by XRD, SEM and TEM. TGA result shows the good thermal stability of the as-prepared LiFeSO4F. No diffraction peaks of the FeSO4 are observed in the as-prepared products with the starting material of either FeSO4?4H2O or FeSO4?7H2O, which should be ascribed to delaying the release of H2O from the hydrated compounds. Cyclic voltammetry (CV) curves and electrochemical impedance spectroscopy (EIS) results prove that the LiFeSO4F/graphene …
