報告摘要：
Electrocatalysis powered by renewable energy is expected to play a pivotal role in the global decarbonization process. In particular, electrocatalytic CO2 and CO reduction reactions (CO(2)RR) are widely considered as indispensable components in the valorization of CO2. Much recent research effort has been devoted to the development of efficient and selective catalysts for valuable C2+ products on Cu surfaces, however, many open questions regarding how species in the electrochemical interfaces impact the activity and selectivity remain. In this lecture, recent efforts in understanding the impact of the surface speciation, adsorbed reaction intermediates and near surface species, including anions and cations, on the CO(2)RR at the molecular level. Mechanistic investigations on the electroreductive C-C coupling reactions leading to C3+ products will also be covered briefly. In-situ/operando surface enhanced vibrational spectroscopies, i.e., surface enhanced infrared and Raman spectroscopies, prove to be enabling tools in the identification of active sites and elucidation of reaction mechanisms. The interconnected nature of species at the electrochemical interface makes the assignment of their individual roles in electrocatalytic processes challenging, but also offers ample opportunities for future interfacial engineering in renewable energy devices.
