  • 摘要:CO2 electroreduction, which coupled the application of renewable electricity, paved a promising way for syngas synthesis. Herein, we demonstrated that Co-based N doped carbon prepared by a simple pyrolysis method provided an ideal platform to generate syngas with tunable ratios of H-2 to CO. During CO2 electroreduction, Co-based N doped carbon exhibited the highest faradaic efficiency (FE) of 56.3% for CO with a total current density of 10.8 mA cm(-2) at -0.9 V versus reversible hydrogen electrode. Structural characterizations showed that the co-existence of Co-0 and Co2+ was responsible for the synthesis of tunable syngas. Notably, we obtained syngas with tunable ratios of H-2 to CO ranging from similar to 1 : 1 to 3 : 1 with the highest current density reaching 47.6 mA cm(-2). This work provides a green way to produce syngas for further applications.
