Abstract

In a typical electrochemical CO₂ reduction system, hydrocarbon products are not selectively generated when a diaphragm is used in the cell. However, without the diaphragm, H₂ and CH₄ are selectively produced with Faradaic efficiencies as high as 96.7% in methanolic NaOH and KOH electrolytes, respectively. We are the first to successfully achieve the selective production of hydrocarbon and hydrogen fuels from the electrochemical reduction of CO₂, which can help to meet the rapidly growing energy demands of modern society.
