  • Doped titanium oxides
    Patent number: 6992042
    Abstract: Pyrogenically prepared titanium dioxide doped by means of an aerosol contains an oxide from the group zinc oxide, platinum oxide, magnesium oxide and/or aluminium oxide as the doping component. It is prepared as follows: in the pyrogenic preparation of titanium dioxide, a metal salt solution is atomised to form an aerosol and injected into the production stream. The titanium dioxide may be used as a photocatalyst or as a UV adsorber or in processes for purification of waste water or waste air/gases.
    Type: Grant
    Filed: May 12, 2003
    Date of Patent: January 31, 2006
    Assignee: Degussa AG
    Inventors: Ina Hemme, Helmut Mangold, Sven-Uwe Geissen, Anna Moiseev

  • Doped titanium dioxide
    Patent number: 6627173
    Abstract: A process for the preparation of doped, pyrogenically prepared titanium dioxide is described. The titanium dioxide is doped with zinc oxide, platinum oxide, magnesium oxide, or aluminium oxide, by injecting an aerosol of the oxide into the production stream. The doped titanium dioxide may be used as a photocatalyst or UV absorber.
