The aim of this study is to quantify the benefits of using a carbon felt electrode modified with reduced graphene-oxide (rgoCF) as a methanogenic biocathode. The current density generated by the rgoCF was almost 30% higher than in the control carbon felt electrode (CF). In addition, charge transfer and ohmic resistances were, on average, 50% lower in the rgoCF electrode. These improvements were accompanied by a larger presence of bacteria (31% larger) and archaea (18% larger) in the rgoCF electrode. The microbial communities were dominated by hydrogenotrophic methanogenic archaea (Methanobacterium) and, to a lesser extent, by a low-diversity group of bacteria in both biocathodes. Finally, it was estimated that for a CO2 feeding rate in the range 15–30 g CO2 per m2 of electrode per day, it is possible to produce a high-quality biogas (>95% methane concentrationSIElsevierIngenieria ElectricaEscuela de Ingenierias Industrial, Informática y Aeroespacial2022info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionhttps://www.sciencedirect.com/science/article/pii/S001623612200816X?via%3Dihubhttp://hdl.handle.net/10612/14528reponame:BULERIA.
