  • Siloxane removal via silicate formation for lifetime extension of photocatalytic devices
    Patent number: 8883084
    Abstract: A photocatalytic device for reacting with volatile organic compounds includes a photocatalyst and at least one additive, such as hafnium oxide and zirconium oxide, that is capable of forming a stable silicate with silicon dioxide. The additive reacts with volatile silicon-containing compounds to form stable silicate compounds. As a result, the silicon-containing compounds are unavailable for deactivation of the photocatalyst.
    Type: Grant
    Filed: July 31, 2007
    Date of Patent: November 11, 2014
    Assignee: Carrier Corporation
    Inventors: Wayde R. Schmidt, Treese Campbell-Hugener, Tania Bhatia
