The study explores the direct conversion of carbonate solutions to ethylene (C₂H₄) using a bipolar membrane (BPM) membrane electrode assembly (MEA) system. The research focuses on enhancing the efficiency of CO₂ reduction and the production of valuable chemicals like ethylene. Key findings include: 1. **Catalyst Development**: The use of Cu–Ag tandem catalysts significantly improves the conversion efficiency of CO₂ to ethylene, achieving a Faradaic efficiency (FE) of up to 10% at a partial current density of 10 mA/cm². 2. **System Stability**: The system maintains near-zero CO₂ concentration in the outlet stream over 24 hours, indicating effective carbon capture and utilization. 3. **Operating Temperature**: Increasing the operating temperature to 50 °C further enhances ethylene production, suggesting thermal management as a potential strategy for improving system performance. 4. **Energy and Environmental Impact**: The study evaluates the energy requirements, CO₂ emissions, and water loss associated with the BPM ethylene production system. While the energy required is significantly higher than traditional naphtha cracking, the system shows promise for carbon neutrality with renewable energy sources. 5. **Conclusion**: The BPM-MEA system demonstrates a promising approach for efficient CO₂ generation and conversion, linking carbon capture technologies to sustainable chemical production. Further research is needed to optimize the system for practical application and reduce environmental impacts.The study explores the direct conversion of carbonate solutions to ethylene (C₂H₄) using a bipolar membrane (BPM) membrane electrode assembly (MEA) system.
