cff-version: 1.2.0 abstract: "Investigation of the combination of a metal electrocatalyst (nickel nanostructures on activated carbon) with a bio-electrocatalyst (mixed anaerobic microbial consortium) for CO2 electroreduction. Biological and abiotic electrochemical experiments, in duplicate, with 3 types of electrodes: without nickel catalyst, with low nickel loading (0.01% wt.), and with high nickel loading (5% wt.). Data includes current density and charge during chronoamperometry experiments, concentration of liquid and gas compounds, optical density, NH4+ nutrient concentration, pH of catholyte, electron recovery calculations, dissolved metal concentration (measured with ICP), and microbial community composition from planktonic samples (characterized with NGS)." authors: - family-names: Chatzipanagiotou given-names: Konstantina-Roxani orcid: "https://orcid.org/0000-0002-5565-9406" - family-names: Jourdin given-names: L. orcid: "https://orcid.org/0000-0002-6572-1154" - family-names: Strik given-names: David P.
