  • Patent number: 8148293
    Abstract: Highly uniform cluster based nanocatalysts supported on technologically relevant supports were synthesized for reactions of top industrial relevance. The Pt-cluster based catalysts outperformed the very best reported ODHP catalyst in both activity (by up to two orders of magnitude higher turn-over frequencies) and in selectivity. The results clearly demonstrate that highly dispersed ultra-small Pt clusters precisely localized on high-surface area supports can lead to affordable new catalysts for highly efficient and economic propene production, including considerably simplified separation of the final product. The combined GISAXS-mass spectrometry provides an excellent tool to monitor the evolution of size and shape of nanocatalyst at action under realistic conditions. Also provided are sub-nanometer gold and sub-nanometer to few nm size-selected silver catalysts which possess size dependent tunable catalytic properties in the epoxidation of alkenes.

  • Patent number: 7582276
    Abstract: The invention relates to nanoscale rutile or oxide powder that is obtained by producing amorphous TiO2 by mixing an alcoholic solution with a titanium alcoholate and with an aluminum alcohalate and adding water and acid. The amorphous, aluminum-containing TiO2 is isolated by removing the solvent, and is redispersed in water in the presence of a tin salt. Thermal or hydrothermal post-processing yields rutile or oxide that can be redispersed to primary particle size. The n-rutile or the obtained oxide having a primary particle size ranging between 5 and 20 nm can be incorporated into all organic matrices so that they remain transparent. Photocatalytic activity is suppressed by lattice doping with trivalent ions. If the amorphous precursor is redispersed in alcohol, or not isolated, but immediately crystallized, an anatase is obtained that can be redispersed to primary particle size.
