TL;DR: A copper electrocatalyst at an abrupt reaction interface in an alkaline electrolyte reduces CO2 to ethylene with 70% faradaic efficiency at a potential of −0.55 volts versus a reversible hydrogen electrode (RHE).

TL;DR: It is reported that nanostructured electrodes produce, at low applied overpotentials, local high electric fields that concentrate electrolyte cations, which leads to a high local concentration of CO2 close to the active CO2 reduction reaction surface, which surpasses by an order of magnitude the performance of the best gold nanorods, nanoparticles and oxide-derived noble metal catalysts.

TL;DR: A catalyst:ionomer bulk heterojunction (CIBH) architecture that decouples gas, ion, and electron transport and achieves CO2 electroreduction on copper in 7 M potassium hydroxide electrolyte with an ethylene partial current density at 45% cathodic energy efficiency.

TL;DR: Simulations show that the ability to tune the average oxidation state of copper enables control over CO adsorption and dimerization, and makes it possible to implement a preference for the electrosynthesis of C2 products.

TL;DR: A techno-economic analysis is presented with the goal of identifying maximally profitable products and the performance targets that must be met to ensure economic viability-metrics that include current density, Faradaic efficiency, energy efficiency, and stability.
