Abstract:<\/b><\/p>\n

\n

Electrochemical C\u2014N coupling has emerged as a promising strategy for the sustainable synthesis of nitrogen-containing chemicals. However, controlling C\u2014N bond formation remains challenging due to the complexity of electrochemical reaction pathways, competing reactions, and the dynamic nature of electrocatalyst surfaces under operating conditions.<\/p>\n

This presentation discusses the challenges and opportunities associated with electrochemical C\u2014N coupling, with a particular focus on a Cu2O\/ZnO-based electrocatalyst. Emphasis is placed on understanding the relationship between catalyst structure, active sites, and reaction intermediates, as well as on the dynamic evolution of the catalyst surface under electrochemical conditions. In situ and operando vibrational spectroscopic techniques are employed to investigate the evolution of surface species and reaction intermediates during electrochemical C\u2014N coupling. The spectroscopic results provide insights into changes occurring at the catalyst-electrolyte interface and contribute to the identification of species potentially involved in C\u2014N bond formation. Particular attention is given to the evolution of the Cu2O\/ZnO catalyst under reaction conditions.<\/p>\n

The presentation highlights the opportunities offered by combining electrochemical measurements with vibrational spectroscopy to establish connections between catalyst evolution, active sites and reaction intermediates. Such an approach provides a basis for a deeper understanding of C\u2014N coupling mechanisms and for the rational development of electrocatalysts with improved performance.<\/p>\n
