英文摘要: Graphical abstract: The electrochemical production of syngas would enable production of chemicals and transportation fuels from carbon dioxide, water and renewable energy, but a suitable process at the moment does not exist. In this paper we consider two options for syngas production: (i) CO2 electrolysis to produce CO, water electrolysis to produce H2 and then mixing the CO and H2 to yield syngas; and (ii) the simultaneous co-electrolysis of CO2 and H2O in a single electrolyzer. The results show that both processes can produce syngas at industrially important rates. In this paper we demonstrate CO2 electrolysis at 100mA/cm2, i.e., about 20turnovers/s, and water electrolysis at 8A/cm2 at 2.0V/cell, with about 1,600turnovers/s. Both systems are stable for a thousand hours or more, i.e., millions of turnovers. We also demonstrate simultaneous CO and H2 production in a single electrolyzer. These results demonstrate that syngas can be produced at industrially important rates via electrolysis. © 2016 Elsevier Ltd. Citation statistics:
