  • Photocatalytic nanocomposites and applications thereof
    Patent number: 7541509
    Abstract: A photocatalyst nanocomposite which can be used to destroying biological agents includes a carbon nanotube core, and a photocatalyst coating layer covalently or ionically bound to a surface of the nanotube core. The coating layer has a nanoscale thickness. A method of forming photocatalytic nanocomposites includes the steps of providing a plurality of dispersed carbon nanotubes, chemically oxidizing the nanotubes under conditions to produce surface functionalized nanotubes to provide C and O including groups thereon which form ionic or covalent bonds to metal oxides, and processing a metal oxide photocatalyst sol-gel precursor in the presence of the nanotubes, wherein a nanoscale metal oxide photocatalyst layer becomes covalently or ionically bound to the nanotubes.
    Type: Grant
    Filed: August 31, 2005
    Date of Patent: June 2, 2009
    Assignee: University of Florida Research Foundation, Inc.
    Inventors: Wolfgang M. Sigmund, Sung-Hwan Lee, Benjamin Koopman, Brij Moudgil, Georgios Pyrgiotakis, Vijay Krishna
