Ni Single Atoms and Reconstructed Cu Single Clusters Enable Tandem Electrocatalysis for CO2 to Acetone Conversion
Researchers have developed a novel tandem electrocatalysis system utilizing nickel single atoms and reconstructed copper single clusters to efficiently convert carbon dioxide (CO2) into acetone. This innovative approach addresses key challenges in CO2 reduction, aiming for higher selectivity and energy efficiency. The system's design leverages the synergistic effects between the precisely engineered nickel and copper active sites. The nickel single atoms are designed to facilitate the initial steps of CO2 activation and reduction, while the reconstructed copper single clusters are optimized for subsequent reactions leading to acetone formation. This tandem configuration allows for a more controlled and efficient multi-step reaction pathway. The study highlights the potential of single-atom catalysis and carefully designed cluster structures in advancing electrochemical CO2 conversion technologies. This breakthrough could pave the way for more sustainable chemical synthesis processes, converting a greenhouse gas into a valuable chemical feedstock. Further research will focus on scaling up the process and improving long-term stability under industrial operating conditions.
