Preparation of microvillus-like nitrogen-doped carbon nanotubes as the cathode of a microbial fuel cell

Abstract

The efficiency of a microbial fuel cell (MFC) generally suffers from its poor cathode performance. To improve this, a novel cathode material was prepared by growing vertically aligned nitrogen-doped carbon nanotubes on carbon cloth, offering an efficient, metal-free, and low-cost alternative to Pt/C.
