Nitrogen doping boosted aqueous Zn-CO2 batteries producing methane and electricity simultaneously

Key Points

• The aim is to enhance the performance of aqueous Zn-CO2 batteries through nitrogen doping to improve CO2 reduction.
• Developed a nitrogen-doped Cu-based metal-organic framework (N-Cu-MOF) as the cathode.
• Evaluated the performance of the N-Cu-MOF cathode in Zn-CO2 batteries.
• Measured methane production and electricity generation outputs.
• N-Cu-MOF significantly increased electrochemical CO2 reduction efficiency.
• Observed a marked improvement in power density compared to traditional cathodes.
• Enhanced simultaneous production of methane while generating electricity.
