▎ 摘　　要

NOVELTY - A microorganism extracellular electronic transfer strengthening method involves utilizing graphene or aza-graphene supported on a carbon electrode as an anode, where the graphene or aza-graphene is directly loaded to the carbon electrode by electrophoretic deposition. USE - Method for strengthening microorganism extracellular electronic transfer. ADVANTAGE - The method enables strengthening the microorganism extracellular electronic transfer with better electricity generating effect in simple and cost-effective manner. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a microbial electrochemical system (2) a microorganism extracellular electronic transfer is strengthened by the method.
