  • Room temperature synthesis of multiwalled carbon nanostructures
    Patent number: 7132126
    Abstract: A simple chemical technique has been developed to grow large quantity of carbon nanostructures, including carbon nanotubes, hydrocarbon nanotubes and carbon nanoonions, in the organic solution at ambient (room) temperature and atmospheric pressure using silicon nanostructures (nanowires, nanodots, ribbons, and porous silicon) as starting materials. These CNT and CNO have the lattice d-spacing from 3.4 ? to 5 ?.
    Type: Grant
    Filed: October 17, 2002
    Date of Patent: November 7, 2006
    Assignee: City University of Hong Kong
    Inventors: Shuit-Tong Lee, Chi-Pui Li, Xu-Hui Sun, Ning-Bew Wong, Chun-Sing Lee, Boon-Keng Teo
