Led by the University of Illinois Urbana-Champaign Chemistry Progressor Andrew Gewirth and Graduate Student Xinyi Chen, the study reports that by allowing CO2 to flow through a reaction chamber fitter with copper electrodes and an electrolyte solution is the most common method researchers use to convert CO2 to useful carbon-containing chemicals. “Copper metal is highly selective toward the type of carbon that forms ethylene. Different electrode materials will produce different chemicals like carbon monoxide instead of ethylene, or a mix of other carbon chemicals. What we have done in this study is to design a new kind of copper electrode that produces almost entirely ethylene,” Gewirth said.
