Modification of PPy-NW anode by carbon dots for high-performance mini-microbial fuel cells

To boost the performance of microbial fuel cells (MFCs), a novel material of polypyrrole nanowires (PPy-NWs) modified by carbon dots (CDs) is synthesized by polymerizing pyrrole monomers and CDs, in which CDs are attached and distributed on the surface of the PPy-NWs, thus leading to the rough surfa...
