  • Electrically conductive diamond electrodes
    Patent number: 7534296
    Abstract: An electrically conductive diamond electrode and process for preparation thereof is described. The electrode comprises diamond particles coated with electrically conductive doped diamond preferably by chemical vapor deposition which are held together with a binder. The electrodes are useful for oxidation reduction in gas, such as hydrogen generation by electrolysis.
    Type: Grant
    Filed: March 17, 2006
    Date of Patent: May 19, 2009
    Assignee: Board of Trustees of Michigan State University
    Inventors: Greg Swain, Anne Fischer, Jason Bennett, Michael Lowe

  • Electrically conductive polycrystalline diamond and particulate metal based electrodes
    Publication number: 20050200260
    Abstract: An electrically conducting and dimensionally stable diamond (12, 14) and metal particle (13) electrode produced by electrodepositing the metal on the diamond is described. The electrode is particularly useful in harsh chemical environments and at high current densities and potentials. The electrode is particularly useful for generating hydrogen, and for reducing oxygen and oxidizing methanol in reactions which are of importance in fuel cells.

  • Boron-doped nanocrystalline diamond
    Publication number: 20050110024
    Abstract: A conductive boron doped nanocrystalline diamond is described. The boron doped diamond has a conductivity which uses the boron in the crystals as a charge carrier. The diamond is particularly useful for electrochemical electrodes in oxidation-reduction reactions and decontamination of aqueous solutions.
