Turning CO2 to Carbon Nanofibers

Turning CO2 to Carbon Nanofibers
Aug-25-15
A new technique that captures carbon dioxide from the atmosphere and turns it into carbon nanofibers is being referred to as “diamonds from the sky.”

The technique, developed at George Washington University, takes the captured carbon dioxide and immerses it in molten carbonates heated to 1,380° F. Air and an electrical current transferred via nickel and steel electrodes is then sent into the material, which causes the CO2 to dissolve as the nanofibers cluster on the steel electrode. The method also requires very little energy (a small as a single volt) and relies on solar cells and a thermal energy collector to heat the carbonate bath.
