Polyaniline-decorated honeycomb-like structured macroporous carbon composite as an anode modifier for enhanced bioelectricity generation[url=https://www.wyactivatedcarbon.com/]https://www.wyactivatedcarbon.com/[/url] The design of high-performance anodes for bioelectricity generation remains a challenge in microbial fuel cells (MFCs). In the present work, we found that sodium citrate-derived carbon (SC) with a honeycomb-like macroporous structure could be prepared by a facile pyrolysis method. Then, a novel electrode fabricated by in-situ polymerization of polyaniline (PANI) nanoparticles on the SC-loaded carbon paper (CP), named PANI@SC-CP electrode, was used as the anode in electrochemical cells (ECs); this configuration resulted in much higher anodic current density than that of the control CP electrode. This improvement was attributed to the higher biocapacity resulting from the large Brunauer-Emmett-Teller (BET) surface area of the SC, the outstanding hydrophilicity of PANI, [url=https://www.wyactivatedcarbon.com/products/other-activated-carbon/honeycomb-activated-carbon.html]honeycomb active carbon[/url]and the increased extracellular electron transfer efficiency owing to the good conductivity and the excellent electrochemical activity of the PANI@SC-CP electrode as well as the enhanced interaction between the electroactive microbes and the electrode triggered by the combination of PANI and SC. The excellent performance of the PANI@SC-CP anode for bioelectricity generation was also demonstrated in MFCs inoculated with a pure or mixed culture.
