[Abstract]

Transition-metal single atom catalysts have been demonstrated as promising catalysts for selective electrochemical CO2 reduction reaction (CO2RR), however, neither the detailed structures of catalytic intermediates nor the key surface species have been unambiguously identified. In this work, a series of single transition-metal atom catalysts with well-defined structures were developed as model systems to explore the electrochemical CO2RR chemistry. Employing a combination of operando X-ray absorption spectroscopy, attenuated total reflectance surface enhanced infrared absorption spectroscopy, Raman spectroscopy and Mössbauer spectroscopy, we successfully captured the dynamic evolution of the catalytic centers during the CO2RR process.
