Micro/nano Mo2C-C as anode electrocatalyst for high-performance microbial fuel cells
Mo2C-C composites with micro-/nanostructure as high-performance anode electrocatalyst for microbial fuel cells(MFCs)were successfully prepared by a simple solution derived precursor and calcination method.Morphological and compositional charac-terization indicate that the prepared Mo2C-C composites consisted of Mo2C and C with micro/nanoparticle structure and rich func-tional groups on the surface,improving the attachment of microorganisms on the anode surface.Electrochemical measurements dem-onstrated that the as-synthesized micro/nano Mo2C-C composites exhibited an outstanding electrocatalytic activity for charge transfer between anode/microorganisms.The MFC fitted with micro/nano Mo2C-C/CF anode harvested a superior power density(1.61 W·m-2),significantly higher than that of commercial carbon felt anode.This work provides new ideas for high performance and envi-ronmentally friendly MFC anode electrocatalysts.
