| Abstract Scope |
Limited power output in bioelectrochemical systems (BESs) is caused by poor electrical conductivity and weak attachment of microbes to the anode. This hinders the flow of electrons between the microbes and the anode.
This study investigated coating a graphite felt anode with copper metal-organic framework (Cu-MOF) and a combination of Cu-MOF and polyaniline (PANI). XRD, FTIR and SEM confirmed that the Cu-MOF was successfully synthesized. Additionally, the Cu-MOF showed improved properties for electricity generation with better conductivity and improved bacterial attachment.
Most importantly, the BES with the Cu-MOF/PANI coated anode produced significantly more power (133 mW/mē) compared to the one with a plain graphite felt anode (33 mW/mē). This improvement is likely due to easier electron transfer from microbes and provides a more favorable environment for electroactive microbes to grow on anode.
These findings suggest that Cu-MOF/PANI coated anodes are a promising approach to enhance the power output of BESs. |
