Summary
Researchers at Argonne National Laboratory say they’ve found a breakthrough way to recycle carbon dioxide into energy-rich ethanol fuel. The secret is an electrified catalyst made from copper and carbon, which the researchers say can be powered using low-cost off-peak or renewable energy.

Summary
By an electrochemical reaction, this catalyst breaks down carbon dioxide and water molecules and selectively reassembles the broken molecules into ethanol under an external electric field.
Previous attempts at this process often aren’t very good at fully converting the carbon dioxide.
