Tailoring Unique Mesopores of Hierarchically Porous Structures for Fast Direct Electrochemistry in Microbial Fuel Cells

Abstract

A highly biocompatible, hierarchically porous structure comprising macro-, meso- or micropores from cost-effective bacterial cellulose through a facile carbonization approach, is tailored for its nanopore structure to disclose the mechanism in a porous electrode to enhance direct electrochemistry through endogenous mediator-based electron transfer between microbes and electrode. The unique mediator-accessible mesopore structure is necessary to greatly boost anode bioelectrocatalysis.
