  • Patent number: 11389788
    Abstract: Provided is a scalable delamination of a SSZ-70 framework zeolite, without the need for sonication, which has been previously made difficult by the charged nature of the imidazolium structure-directing agents that are required for zeolite synthesis. The method comprises contacting a B-SSZ-70 zeolite precursor with a zinc source such as zinc nitrate and a fluoride source.

  • Patent number: 10898887
    Abstract: In one example, a method for converting a first compound into a second compound is provided. The method includes providing the first compound in an entrance of a flow through reactor, wherein the entrance comprises a first catalyst and an oxidant, converting the first compound and the oxidant into the second compound as the first compound and the oxidant contact the first catalyst in the entrance of the flow through reactor while moving towards a tail end of the flow through reactor, and converting the first compound and the oxidant into the second compound via a solid catalyst comprising a white crystalline solid with a titanium content of about 0.5 to about 1.5 weight percent (wt %) in the tail end of the flow through reactor.

  • Patent number: 9575042
    Abstract: Provided is an organic ligand-bound metal surface that selects one gaseous species over another. The species can be closely sized molecular species having less than 1 Angstrom difference in kinetic diameter. In one embodiment, the species comprise carbon monoxide and ethylene. Such organic ligand-bound metal surfaces can be successfully used in gas phase separations or purifications, sensing, and in catalysis.

  • Patent number: 9266915
    Abstract: The present invention is directed to the synthesis of novel stable open metal clusters by selective oxidation of bound ligands. The synthesis comprises, for example, using an amine based oxidant for decarbonylation of specific carbonyl ligands. The synthesis can also comprise further removal of a bound amine group by an acid. The resulting metal cluster contains a coordinatively unsaturated site comprising a carbonyl vacancy. The resulting metal cluster can be used as a catalyst in a variety of chemical transformations.

  • Publication number: 20140121427
    Abstract: The present invention is directed to the activation of metal carbonyl clusters by an oxidative agent to prepare a stable metal cluster catalyst exhibiting catalytic rate enhancement. The activation comprises, for example, using oxygen for decarbonylation of carbonyl ligands and changing the oxidation state of the other ligands. In one aspect, treatment of the metal cluster catalyst under oxidative conditions in a flow reactor leads to removal of CO ligands and oxidation of bound calixarene phosphine ligands, and results in a stable activated open metal cluster that is more active for ethylene hydrogenation catalysis. The resulting metal cluster contains coordinatively unsaturated sites comprising carbonyl vacancies. In one aspect, the resulting activated open metal cluster can be used as a catalyst in a variety of chemical transformations.
