GWU team demonstrates highly scalable, low-cost process for making carbon nanotube wools directly from CO2

By mmillikin Researchers at George Washington University led by Dr. Stuart Licht have demonstrated the first facile high-yield, low-energy synthesis of macroscopic length carbon nanotubes (CNTs)—carbon nanotube wool—from CO2 using molten carbonate electrolysis (earlier post).

The resulting CNT wool is of length suitable for weaving into carbon composites and textiles and is highly conductive; the calculated cost to produce the CNTs is approximately $660 per ton, compared to the current $100,000+ per ton price range of CNTs. A paper on the work is published in the journal Materials Today Energy.

The CNT wool process builds on earlier work by Professor Licht and his team
