| 제목 | Bioelectrosynthetic Conversion of CO2 Using Different Redox Mediators: Electron and Carbon Balances in a Bioelectrochemical System |
| 초록 | Microbialelectrosynthesis (MES) can convert CO2 to acetate and other value-addedchemicals using electricity as the reducing power. Several redox mediators can enhance interfacial electron transport betweenbacteria and the electrode in MES systems. In this study, different redoxmediators, such as neutral red (NR), 2-hydroxy-1,4-naphthoquinone (HNQ), andhydroquinone (HQ), were compared to facilitate an MES-based CO2 reductionreaction on the cathode. The mediators, NR and HNQ, improved acetate productionfrom CO2 (165 mM and 161 mM, respectively) compared to the control (without amediator = 149 mM). On theother hand, when mediators were used, the electron and carbon recoveryefficiency decreased because of the presence of bioelectrochemical reductionpathways other than acetate production. Theseresults suggest that the addition of mediators to MES can improve CO2conversion to acetate with further optimization in an operating strategy ofelectrosynthesis processes. |
