Researchers at MIT have discovered a way to make copper turn carbon dioxide into hydrocarbon fuels, with help of just a little bit of gold.
When copper is stimulated with voltage, it acts as a strong catalyst that sets off an electrochemical reaction with carbon dioxide that reduces the greenhouse gas to methane or methanol. But the problem was that copper is temperamental and oxidize too easily. Copper is inherently unstable, which significantly slows down the reaction with carbon dioxide by producing unwanted byproducts.
