“…It was considered as green energy source and energy-saving environment treatment process due to the integration of environmental bioremediation with energy generation (Li et In order to meet the requirement of the MFC performance improvement, various nanostructured materials have been developed for anode surface modification (Qiao et al, 2008;Qiao et al, 2007;Yong et al, 2012). Among them, polyaniline is of great interest due to its low cost, simple synthesis process, excellent electrochemical activity and biocompatibility (Lai et al, 2011;Li et al, 2011;Yuan et al, 2013). The morphology and chemical properties of polyaniline can be easily tuned by varying the 4 polymerization parameters (Chiou et al, 2007;Guo et al, 2011).…”
