Improving trade-offs in the figures of merit of gas-phase single-pass continuous CO2 electrocatalytic reduction to formate

The electrochemical conversion of CO2 is gaining increasing attention because it could be considered as an appealing strategy for making value-added products at mild conditions from captured. In this work, we report a process the electrocatalytic reduction to formate (HCOO?) operating in continuous way, employing single pass reactants through reactor and using Bi carbon supported nanoparticles form membrane electrode assembly composed by Gas Diffusion Electrode, current collector cationic exchange membrane. This contribution presents best trade-off between HCOO? concentration, Faradaic Efficiency energy consumption literature. We also show noteworthy values required only 180 kWh·kmol?1 HCOO?, lower than previous approaches, working densities that allow achieving concentration higher 300 g·L?1 simultaneously, close 90%. results here displayed make approach closer future implementation industrial scale.
