  • Method for producing encapsulated nanoparticles and carbon nanotubes using catalytic disproportionation of carbon monoxide and the nanoencapsulates and nanotubes formed thereby
    Patent number: 5965267
    Abstract: A method for the production of carbon encapsulated nanoparticles, carbon nanotubes and other closed carbon structures, including contacting a catalyst of a transition metal, or a compound or alloy thereof, with a gas mixture containing carbon monoxide, and an amount of available molecular hydrogen which is insufficient to cause formation of graphite plane edges through capping, at a temperature in the range from 300-1000.degree. C., to provide closed carbon structures, which are useful in the preparation of thermal composites, reinforcement composites and magnetic particle recording media.
    Type: Grant
    Filed: March 31, 1998
    Date of Patent: October 12, 1999
    Assignee: Arizona Board of Regents on behalf of the University of Arizona
    Inventors: Peter E. Nolan, Andrew H. Cutler, David G. Lynch
