Patent number: 8034408Abstract: Metal powder (such as tin, titanium, or tungsten powder) is heated in a flowing stream of an inert gas, such as argon, containing a small abundance of oxygen at a temperature to produce metal vapor. The metal reacts with the oxygen to form and deposit one-dimensional nanostructures of oxygen-containing metal on the metal powder (in the case of Ti and W) or on a suitable nearby substrate in the case of the lower melting tin. The metal oxides are not necessarily stoichiometric compounds. Water may be introduced into the flowing inert gas to increase or control the oxygen content. Sulfur vapor or a carbon source may be introduced to dope the nanostructures with sulfur or carbon. Reaction conditions may be modified to vary the shapes of the one-dimensional nanostructures.Type: GrantFiled: September 6, 2007Date of Patent: October 11, 2011Assignees: GM Global Technology Operations LLC, University of Western OntarioInventors: Xueliang Sun, Ruying Li, Yuqin Zhou, Mei Cai, Hao Liu
