Direct Synthesis of 1-Butanol with High Faradaic Efficiency from CO Utilizing Cascade Catalysis at a Ni-Enhanced (CrO)GaO Electrocatalyst.

Electrochemical transformation of CO into energy-dense liquid fuels provides a viable solution to challenges regarding climate change and nonrenewable resource dependence. Here, we report on the modification of a Cr-Ga oxide electrocatalyst through the introduction of nickel to generate a catalyst that generates 1-butanol at unprecedented faradaic efficiencies (ξ = 42%). This faradaic efficiency occurs at -1.
