Macroporous monolithic Magnéli-phase titanium suboxides as anode material for effective bioelectricity generation in microbial fuel cells

Abstract

A macroporous monolithic ceramic anode material based on Magnéli-phase titanium suboxides, fabricated by a facile method, is able to effectively generate bioelectricity in microbial fuel cells (MFCs). Owing to their highly active surface area and efficient extracellular electron transfer from electricigens to the anode, MFCs can achieve a peak biocurrent time of 37 h with a maximum power density of 1541 ± 18 mW m⁻².
