“…[86,87,89] For example, it is said that plasmaoxidation pre-treatment can increase CO selectivity of Ag foil by enhancing the number of low-coordinated active sites, which shows a CO selectivity of more than 90% Faradaic efficiency (FE) at −0.6 V versus RHE. [90] Moreover, planar defects like stacking faults, [91] interfaces, [92] grain boundaries, [93] stepped surfaces [94] and twin boundaries [95] also show benefits to CO 2 activation and reduction. By means of UHV calculations, it is proposed that the grain boundary engineering is a promising strategy to tune the activity and selectivity of Au catalysts toward CO production, via enhancing *CO binding strength on the grain boundary sites of Au (110) surface.…”

Electrocatalysis for CO2 conversion has been extensively studied to mitigate the energy shortage and environmental issues, which are gaining ever‐increasing attention. However, the complicated CO2 reduction process and the dynamic evolution occurring on electrocatalyst surface make it hard to understand the catalytic mechanism. The development of advanced in situ/operando techniques intelligently coupled with electrochemical cells sheds light on the related study via capturing surface atomic rearrangement, tracing chemical state change of catalysts, monitoring the behavior of intermediates and products, and depicting microenvironment near the electrode surface. In this review, fundamentals of the state‐of‐the‐art in situ/operando techniques are clarified first. Case studies on the in situ/operando techniques performed to probe the CO2 reduction reaction processes are then discussed in detail. Finally, conclusions and outlook on this field are presented.

“…And, the activity and instability of Cu‐based catalysts also makes for the reconstruction phenomena during the electrochemical process, which aggravates the existence of Cu‐based heterojunction. [ 255 ] Therefore, the control of type and quantity of Cu‐based heterojunction is a nonnegligible factor for the regulation of multicarbon selectivity. The stable Cu 0 ─Cu x + interfaces are derived from the low‐coordinated Cu atoms on the edge or the corner of the surface of catalysts during the electrochemical process.…”

The electrochemical CO2 (eCO2)‐to‐multicarbon conversion with higher value is regarded as a potential way to promote the transformation of industrial production and the green balance of carbon cycle. Recently, a series of advances have been achieved in the progress of eCO2‐to‐multicarbon conversion, including the in‐depth exploration of coupling mechanisms, the up‐to‐date development of characterization techniques, and the novel interdisciplinary design strategies of catalysts and electrolytic systems. Therefore, it is essential to systematically overview the eCO2‐to‐multicarbon conversion from fundamentals to industrialization, compensating for the limited and insufficient reviews that have been reported. To fill the aforementioned research gap, this overview is focused on the eCO2‐to‐multicarbon conversion from fundamentals to industrialization. First, the possible catalytic mechanisms for eCO2‐to‐multicarbon conversion are accordingly summarized in the order of eCO2 reduction, small molecule‐coupled eCO2 reduction, and eCO2 tandem conversion. Second, the up‐to‐date in situ characterization technologies assisting the rationalization of coupling mechanisms are presented. Third, the optimizing strategies of catalysts and electrolytic systems are briefly classified for the advance of industrialization process. Finally, challenges and perspectives for the further development of eCO2‐to‐multicarbon conversion are reasonably proposed, aiming to offer insights for the following work in this field.

“…Al was selected due to its high selectivity toward C 2+ products by alloying and forming interfaces with Cu. 12,42,43 Highly porous metal-organic frameworks (MOFs) were used to introduce Al into CuO. Surprisingly, rough nanoparticles of Al-doped CuO (CuO_Al) were reconstructed into nanoakes under the eCO 2 RR, which was not the case for CuO.…”
