Abstract The co‐electroreduction of CO 2 and NO x ⁻ (NO 3 ⁻/NO ⁻) to generate formamide (HCONH ) offers an opportunity for downstream chemical polymer manufacturing decarbonization; however, significant challenges lie in the C‒N coupling associated low product selectivity. Herein, p ‐block metal oxides are incorporated copper provide more accessible active sites reactant adsorption activation, tuning reaction selectivity toward production. Through situ Raman synchrotron‐based infrared spectroscopy measurements, C─N bond formation is demonstrated real‐time with CuO /BiO catalyst, where detected via a *CHO *NH intermediates formation, agreement density functional theory calculations. When tested flow electrolyzer, yield rate 134 ± 11 mmol h −1 g cat reported, first report beyond conventional H‐cell measurements.

Tin effective electrocatalyst CO2R formate, but underlying reaction mechanism whether active phase of tin metallic or oxidized during openly debated. In this report, we used grand-canonical density functional theory attenuated total reflection surface-enhanced infrared absorption spectroscopy identify differences in vibrational signatures surface species on fully surfaces. Our results show that feasible both tin. We propose key difference between each termination catalyzed by surfaces limited electrochemical activation CO2, whereas slow reductive desorption formate.

A prominent feature of modern electrochemical technologies, such as fuel cells and electrolysis, is the employing polyelectrolytes instead liquid electrolytes. Unlike well-studied electrode/liquid electrolyte interfaces, however, catalytic characteristics electrode/polyelectrolyte interfaces remain largely unexplored, mostly due to lack reliable probing methods. Herein, we report a universally applicable approach investigating electrocatalytic reactions at under normal conditions. By coating thin layer anion-exchange membrane (AEM) onto electrode surface, solutions with bulky organic cations were well separated, thus pure interface can be established in regular setup studied using situ spectroscopies, e.g., attenuated total reflectance surface-enhanced infrared absorption spectroscopy (ATR-SEIRAS). We found that blank Au surface was inert toward CO2 reduction reaction (CO2RR) absence alkali metal cations, whereas an AEM dramatically turn on activity. ATR-SEIRAS revealed hydrogen bond network water Au/AEM enhanced comparison which facilitated hydrogenation process CO2RR. These findings further our fundamental understanding behavior benefit development relevant technologies.
