Accidental CO2 conversion

US researchers have serendipitously discovered a nanostructured electrocatalyst made from carbon and copper that can convert aqueous carbon dioxide to ethanol with a staggering yield of more than 60%. The process might ultimately be scaled up to scrub the greenhouse gas from fossil fuel power station emissions or other carbon dioxide sources. The process would generate a cleaner form of fuel or if driven by solar, wind or other sustainable electricity source could be used as chemical storage for power.
