“…63 Most current CO 2 RR techniques focus on the production of C 1 products as they are more kinetically favorable. 64 The majority of the products are CO or formic acid since it involves simple reactions to produce CO or HCOOH, and the catalysts This journal is © The Royal Society of Chemistry 2023 have weak bindings towards the intermediates such as *CO and *COOH. 62 SACs were reported to be efficient in producing C 1 products at low overpotentials.…”

“…Research endeavors to steer the reaction toward better C 2 selectivity have provided new insights into the role of modifying the electrolyte and/or microenvironment, catalyst faceting, , roughening the surface, , introducing mixed-valence copper species, nanostructuring the catalyst to introduce defects or to confine intermediates, and pulsing the applied voltage. Future endeavors to bring these advances to fruition stand to benefit from answers to outstanding questions about the fundamental mechanisms within the complex reaction network. Computational studies, particularly density functional theory (DFT) calculations of binding and activation energies, continue to provide detailed information into the energetics and possible reaction pathways.…”

“…CO 2 is characterized by strong C–O bonds, making this compound very stable and inert, requiring a significant amount of energy for its activation . Processes to convert CO 2 into high-value products have been multifaceted, including thermal catalysis, and photo- and electro-catalysis. Among these, electrocatalytic processes have shown promise, since product selectivities and yields from CO 2 can be tuned through adjusting the applied potential under mild reaction conditions, while circumventing the complexity of photocatalytic systems associated with direct coupling of photon and electron processes. Different types of electrochemical systems have been investigated for CO 2 electroreduction over the years. ,, This review mainly focuses on high-temperature electrochemical reduction using solid oxide electrolysis cells (SOECs) for converting CO 2 selectively to CO. CO is a valuable platform chemical with a wide range of industrial applications: for example, the synthesis of acetic acid by catalytic carbonylation of methanol and the production of formic acid by hydrolysis of methyl formate. CO can also be coupled with H 2 and converted to liquid hydrocarbons using Fischer–Tropsch synthesis. , The electrochemistry at the solid/gas interface of the SOEC cathode is generally simpler than that of low-temperature electrochemical systems at solid/liquid interfaces .…”
