  • Publication number: 20120149560
    Abstract: Provided is a method of manufacturing porous metal oxide, the method including: preparing a metal-organic framework (MOF) wherein an ion of a metal to be used as a catalyst is linked to an organic ligand; impregnating the MOF with a precursor solution of metal oxide to be manufactured; and thermally treating the metal oxide precursor solution-impregnated MOF to remove the organic ligand. The inventive method of manufacturing porous metal oxide involves the impregnation of a metal oxide precursor solution in a MOF wherein metal ions are uniformly linked to organic ligands and the thermal treatment (calcination) of the metal oxide precursor solution-impregnated MOF to remove the organic ligands.

  • 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.
