Nano-structured textiles as high-performance aqueous cathodes for microbial fuel cells

A carbon nanotube (CNT)–textile–Pt cathode for aqueous-cathode microbial fuel cells (MFCs) was prepared by electrochemically depositing Pt nanoparticles on a CNT–textile. An MFC equipped with a CNT–textile–Pt cathode revealed a 2.14-fold maximum power density with only 19.3% Pt loading, compared to that with a commercial Pt coated carbon cloth cathode.
