AbstractCO2 electroreduction is a potential pathway to achieve net-zero emissions in the chemical industry. Yet, CO2 loss, resulting from (bi)carbonate formation, renders the process energy-intensive. Acidic environments can address the issue but at the expense of compromised product Faradaic efficiencies (FEs), particularly for multi-carbon (C2+) products, as rapid diffusion and migration of protons (H+) favors competing H2 and CO production.

AbstractElectrochemical reduction of carbon monoxide is a promising carbonate-free approach to produce ethylene using renewable electricity. However, the performance of this process suffers from low selectivity and energy efficiency. A priority has been to weaken water dissociation with the aim of inhibiting the competing hydrogen evolution reaction but when this path was examined by replacing H2O with D2O, a further-reduced selectivity toward ethylene was observed.

AbstractElectroreduction of carbon dioxide with renewable electricity holds promise for achieving net-zero carbon emissions. Single-site catalysts have been reported to catalyze carbon-carbon (C-C) coupling—the indispensable step for more valuable multi-carbon (C2+) products—but were proven to be transformed in situ to metallic agglomerations under working conditions.
