Nanocomposite use in MFCs: a state of the art review

“…In response to such a need, the scientific community recently focused on improving the MFC components using nanomaterials, whose unique physical and chemical properties have profoundly improved their performance. 24–30 Besides providing structural resistance 31 and improving the electron transfer rate through the electrode 32 and membrane proton transfer selectivity, 33 their exceptional volume-to-surface ratio can control the microbial adherence and retention on the electrode surface, thereby optimizing the bacterial anode electron transfer. 34 For the cathodic half-cell, nano-modification can provide sufficient porosity to facilitate oxygen diffusion through its surface, enabling higher rates of oxygen reduction reaction (ORR) and consequently, current generation.…”
