Influence of enhanced carbon crystallinity of nanoporous graphite on the cathode performance of microbial fuel cells

We have synthesized a porous graphite with a high degree of local crystallinity by adding copper powder as a catalyst into the magnesiothermic reduction of CO2. Furthermore, we revealed that the enhanced crystallinity of the carbon cathode catalyst promotes the electrochemical performance of microbial fuel cells under neutral pH conditions, which provides future guidance on the selection of carbon catalysts for microbial fuel cells.
