Microbial electrochemical reduction of CO<sub>2</sub>was carried out under two different applied potentials, −0.36 V and −0.66 V<italic>vs.</italic>SHE, using a biological sludge as the inoculum.
The abilities of carbon cloth, graphite plate and stainless steel to form microbial anodes were compared under identical conditions. Each electrode was polarised at −0.2 V vs. SCE in soil leachate fed by successive additions 20 mM acetate. Under these conditions, the maximum current densities provided on average 33.7 A m−2 for 20.6 steel, 9.5 flat graphite. high density obtained with cloth obviously influenced three-dimensional structure. Nevertheless, a fair comparison between electrodes...
Stainless steel is gaining increasing interest as an anodic material in bioelectrochemical systems and beginning to challenge the more conventional carbon-based materials.
The paper introduces the concept of microbial electrochemical snorkel (MES), a simplified design "short-circuited" fuel cell (MFC). MES cannot provide current but it is optimized for wastewater treatment. An electrochemically active biofilm (EAB) was grown on graphite felt under constant polarization in an urban wastewater. Controlling electrode potential and inoculating bioreactor with suspension established EAB improved performance reproducibility anodes. Anodes, colonized by were tested...
Electroactive biofilms were formed from garden compost leachate on platinum wires under constant polarisation at −0.2 V vs.SCE and temperature controlled 40 °C. The oxidation of 10 mM acetate gave maximum current density 7 A m−2 with the electrodes largest diameters (500 1000 μm). smaller diameter exhibited an ultra-microelectrode (UME) effect, which increased up to 66 25 μm electrode. SEM imaging showed around 75 thick 50 wire, while they only 500 Low scan cyclic voltammetry (CV) curves...
