Results in brief
Atomically Dispersed Bifunctional Catalysts for Reversible Zn-CO2 Batteries
From the material point of view. This project has developed two types of cooperative SACs, including Cu-Sn single-atom alloys and Ni-N-C single-atom catalysts, to overcome the performance limits set by the scaling relationship for energy-efficient and selective electrochemical CO2 conversion at industrial-relevant currents. From the mechanism point of view. This project has combined in situ Raman, density function theory simulation, and electrochemical analysis to reveal the reaction pathways and adsorption of intermediates during CO2 conversion, which shed some light for the understanding of CO2 conversion mechanism at single atom limit. From a device point of view. This project has further integrated the SACs into practical membrane electrode assembly full cell, and achieved the state-of-the-art energy efficiency for both CO and formate production. The design and manufacture of cost-effective, safe, and reliable electrochemical CO2 conversion systems are essential to meet current escalating energy demands and mitigate climate change. This project has made substantial improvements to electrochemical CO2 reduction, so they provide higher energy efficiencies (voltages), superior selectivity, and longer service life. Based on these metrics, this technology can potentially provide a cell prototype to store intermittent renewable energy (e.g., solar, wind, and water power) into valuable products (e.g. CO, formate, C2H4), which can be incorporated into grid-scale energy storage systems. New energy storage systems will also offer more flexible, cheap, and efficient energy use for consumers. Overall, the project has achieved the major objectives and milestones for the period, including the development of new single-atom catalysts, the corresponding mechanistic investigations in CO2 conversion, and the development of energy-efficient membrane electrode assembly full cells for CO2 conversion.

Project objective
Atmospheric carbon dioxide (CO2) has increased from 278 to 415 ppm over the industrial period and has critically impacted climate change. Coupling CO2 utilisation with electrochemical energy storage devices, such as metal‐CO2 batteries, represents a promising clean strategy to deal with greenhouse gas effect and energy dilemma simultaneously. We propose to develop an aqueous Zn-CO2 battery prototype based on CO2-HCOOH conversion for high-efficiency energy storage. To achieve this goal, bifunctional Pd-based single-atom catalyst cathodes will be exploited to drive CO2 conversion with high activity and selectivity. We will then probe the reaction mechanism of catalysts by operando analytical tools together with density functional simulations. Moreover, bipolar membrane, gas diffusion electrode, and ionic liquids will be used as alternative approaches to enhance the Zn-CO2 battery performance at cell level. This project is expected to make a significant step forward in the exploitation of single-atom catalysts for CO2 conversion, and accelerate the development of emerging Zn-CO2 batteries. The project also includes a comprehensive training program to enhance the future career prospects of the fellow.
