Research co-led by Berkeley Lab researchers Junko Yano (MBIB) and Ethan Crumlin at the Advanced Light Source (ALS), with collaborators at Caltech’s Joint Center for Artificial Photosynthesis (JCAP), has revealed a surprising driver of a chemical process to reformulate carbon dioxide into more useful compounds. X-ray experiments coupled with theoretical models showed that oxygen atoms near the surface of a copper sample had a more dramatic effect on the early stages of a reaction with carbon dioxide than earlier theories could account for. This work could help make reactions more efficient in converting carbon dioxide into liquid fuels and other products. Read more in the News Center release.
