Turning greenhouse gas into a sustainable energy resource and valuable chemicals

Abstract. Metal–CO₂ batteries represent a promising technology that simultaneously enables energy storage and carbon dioxide utilization, addressing both global energy and climate challenges. However, their practical application is often limited by poor catalytic activity, low selectivity, and insufficient reversibility. Here, we report a Zn–CO₂ battery employing Bi-H₃TATB as an efficient cathode catalyst, which not only facilitates CO₂ electroreduction but also supports rechargeable battery operation in aqueous electrolyte. Electrochemical studies reveal that Bi-H₃TATB delivers high current densities with tunable CO₂RR selectivity, including the formation of multi-carbon products such as ethanol. When integrated into a Zn–CO₂ battery, the system exhibits a stable open-circuit potential of 1.25 V, a maximum power density of 5.8 mW·cm⁻², and reversible charge–discharge performance. These findings highlight Bi-H₃TATB as a multifunctional catalyst for coupling CO₂ conversion with energy storage, advancing the development of sustainable CO₂-based battery technologies.
