  • Visible light activatable photocatalyst
    Patent number: 8551909
    Abstract: A visible light activatable mesoporous titanium dioxide photocatalyst having a surface area of from 100 m2/g to 400 m2/g. The photocatalyst may have a rate of decomposition greater than 0.005 min?1. The photocatalyst may have a band gap width less than 2.95 eV. The photocatalyst may comprise undoped titanium dioxide or doped titanium dioxide. A hydrothermal process for synthesising a photocatalyst is also described.

  • Organosilane Coating Compositions and Use Thereof
    Publication number: 20100330380
    Abstract: A sol-gel coating composition comprising a hydrolysed organosilane, an organometallic precursor and a corrosion inhibitor, wherein the corrosion inhibitor is a chelator for the organometallic precursor. The corrosion inhibitor and the organometallic precursor may form a nanoparticulate complex. The coating composition may comprise one or more additive selected from: an antimicrobial additive, a hardener, a water repelling additive, a dye, a scratch resistant additive and a flexibility enhancing additive. A process for preparing a sol gel coating composition is also described, the process comprising the steps of: hydrolysing an organosilane in the presence of a catalyst; chelating an organometallic precursor; mixing the hydrolysed silane and the chelated organometallic precursor; and hydrolysing the organosilane-organometallic precursor mixture.
