Stanford researchers develop copper-based catalyst that produces ethanol from CO at room temperature; potential for closed-loop CO2-to-fuel process

Green Car Congress

'Researchers at Stanford University have developed a nanocrystalline copper material that produces multi-carbon oxygenates (ethanol, acetate and n-propanol) with up to 57% Faraday efficiency at modest potentials (–0.25?volts to –0.5?volts versus the reversible hydrogen electrode) in CO-saturated alkaline water. The material’s selectivity for oxygenates, with ethanol as the major product, demonstrates the feasibility of a two-step conversion of CO 2 to liquid fuel that could be powered by renewab
