New quantum calculations and computer models show that carbon nanotubes on which atoms of titanium or other transition metals are attached can store hydrogen molecules in numbers more than adequate for efficient hydrogen storage, reports the National Institute of Standards and Technology, Gaithersburg, Md. This capability may enable carbon nantoubes to become a hydrogen source for fuel cells, because it means that carbon nanotubes
with titanium can amass hydrogen in amounts equivalent to 8% of the weight. This amount is one-third better than the 6% minimum storage-capacity ...
