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.
