“…Aljabour et al. studied CO 2 reduction on Co 3 O 4 nanofibers in acetonitrile with small amounts of water (1 % w/v) . In accordance with earlier discussed reaction pathways, they observe that in water containing electrolytes formate is produced, while in pure acetonitrile CO is the main product formed via the disproportionation of CO 2 .− and CO 2 .…”

“…Ternary electrolyte composition have been reported as well. Studies developed by Zhu et al., found that CO 2 reduction in mixtures of ionic liquids, organic solvent and water using Sn and Pb electrodes led to the conversion of CO 2 to HCOOH with a Faradaic efficiency of 91.6 %, higher than reported for the same reaction carried out using a non‐mixed electrolyte . Here, the addition of small amounts of H 2 O, as proton donor, enhanced CO 2 reduction reaction rates.…”

The electrochemical reduction of CO2 to fuels or commodity chemicals is a reaction of high interest for closing the anthropogenic carbon cycle. The role of the electrolyte is of particular interest, as the interplay between the electrocatalytic surface and the electrolyte plays an important role in determining the outcome of the CO2 reduction reaction. Therefore, insights on electrolyte effects on the electrochemical reduction of CO2 are pivotal in designing electrochemical devices that are able to efficiently and selectively convert CO2 into valuable products. Here, we provide an overview of recently obtained insights on electrolyte effects and we discuss how these insights can be used as design parameters for the construction of new electrocatalytic systems.

Electrochemical carbon dioxide reduction reaction (CO2RR) offers a promising way of effectively converting CO2 to value‐added chemicals and fuels by utilizing renewable electricity. To date, the electrochemical reduction of CO2 to single‐carbon products, especially carbon monoxide and formate, has been well achieved. However, the efficient conversion of CO2 to more valuable multicarbon products (e.g., ethylene, ethanol, n‐propanol, and n‐butanol) is difficult and still under intense investigation. Here, recent progresses in the electrochemical CO2 reduction to multicarbon products using copper‐based catalysts are reviewed. First, the mechanism of CO2RR is briefly described. Then, representative approaches of catalyst engineering are introduced toward the formation of multicarbon products in CO2RR, such as composition, morphology, crystal phase, facet, defect, strain, and surface and interface. Subsequently, key aspects of cell engineering for CO2RR, including electrode, electrolyte, and cell design, are also discussed. Finally, recent advances are summarized and some personal perspectives in this research direction are provided.
