Copper clusters capture and convert carbon dioxide to make fuel

Read the full story from Argonne National Laboratory. Capture and convert—this is the motto of carbon dioxide reduction, a process that stops the greenhouse gas before it escapes from chimneys and power plants into the atmosphere and instead turns it into a useful product. One possible end product is methanol, a liquid fuel and the …
