Unified mechanistic understanding of CO2 reduction to CO on transition metal and single atom catalysts

Sudarshan Vijay et al.

Summary: The study investigates the activity of transition metals, metal-nitrogen-doped carbon catalysts, and supported phthalocyanine in the CO2 electroreduction to CO, and presents a unified mechanistic picture. It is found that MNCs have similar electron transfer properties to TMs in CO2 conversion, but can be limited by either CO2 star adsorption or proton-electron transfer reactions. The increased activity of MNC catalysts is attributed to the stabilization of larger adsorbate dipoles due to their discrete and narrow d states.

Selective Reduction of CO2 to CO on an Sb-Modified Cu Electrode: Spontaneous Fabrication and Physical Insight

Hong Li et al.

Summary: By developing a facile galvanic displacement protocol, a copper electrode modified with antimony (Sb) clusters was able to selectively convert CO2 to CO with a Faradaic efficiency of approximately 82% and a stable reduction current for over 12 hours. In situ infrared spectroscopy showed a weaker and red-shifted CO band on the Sb-modified copper electrode compared to the unmodified copper electrode, indicating a change in electronic structure that weakened CO binding strength at copper sites. These findings offer insights for the rational design of high-selectivity CO2RR electrocatalysts through proper interfacial structure engineering.

Determining intrinsic stark tuning rates of adsorbed CO on copper surfaces

Xiaoxia Chang et al.

Summary: The abrupt change in potential between the electrode and the electrolyte acts as the driving force in electrochemical reactions, with the interfacial electric field impacting the stability and reactivity of adsorbed intermediates in surface mediated electrocatalytic reactions. Reliable measurement of the interfacial electric field is crucial in understanding its influence on the rate and product distribution in electrochemical reactions. The vibrational Stark effect can be used to assess the interfacial electric field strength, but may be complicated by the dynamical dipole coupling effect of adsorbates, while the aggregate morphology, rather than the size and shape of individual catalyst particles, has a more prominent impact on the interfacial electric field.
