nano-spike CO2 ethanol

Converting CO2 (+ water + electricity) into ethanol fuel by "nano-spike" catalysis!

Nano-Spike catalysis; discovery of the Oak Ridge National Laboratory made a bit… by chance! The process makes it possible to obtain ethanol from CO2, electricity and water in the presence of a specific nano-catalyst called Nano-Spike. The announced yield on electricity is 60 to 70% which is acceptable on condition that renewable electricity is used (the process […]
