Carbon dioxide to ethanol – A new nano-spike catalyst

Researchers from ORNL found that copper nano-particles supported on carbon nano-spikes can electrochemically catalyse the transformation of carbon dioxide (CO2) to ethanol. These are great news, because because CO2 is a greenhouse gas and ethanol is a fuel, which means we are transforming waste to fuel! Industrially, the process could be used for the storage of excess electricity from renewable energy sources. The CO2 is dissolved in water and the catalyst electrochemically transforms it directly to ethanol. The yield is 63%!
