Electrochemically converting carbon monoxide to liquid fuels by directing selectivity with electrode surface area

Using renewable electricity to convert CO/CO2 into liquid products is touted as a sustainable process to produce fuels and chemicals, yet requires further advances in electrocatalyst understanding, development and device integration. The roughness factor of an electrode has generally been used to increase total rates of production, although rarely as a means to improve selectivity. Here we demonstrate that increasing the roughness factor of Cu …
