Abstract:
Methods for synthesis of hierarchically ordered zeolites and zeolite-type materials are provided. Synthesized hierarchically ordered zeolites and zeolite-type materials formed according to the methods herein possess a high-degree of well-defined long-range mesoporous ordering. The methods include base-mediated reassembly, by dissolution of the parent material to the level of oligomeric structural building units of the parent material, and minimizing or avoiding amorphization/structural collapse. The dissolution and self-assembly is comprehensively controlled to produce hierarchically ordered zeolites and zeolite-type materials according to the methods herein.
Abstract:
Embodiments of the present disclosure describe methods of preparing pre-catalysts that may be activated under methane to form catalysts for the hydrogenation of carbon dioxide to form olefins, among other chemical species. Embodiments of the present disclosure also describe methods of preparing catalysts and pre-catalysts, catalyst and pre-catalyst compositions, and methods of producing one or more chemical species using catalysts.
Abstract:
The invention describes phospho-amino pincer-type ligands, metal complexes thereof, and catalytic methods comprising such metal complexes for conversion of carbon dioxide to methanol, conversion of aldehydes into alcohols, conversion of aldehydes in the presence of a trifluoromethylation agent into trifluorinated secondary alcohols, cycloaddition of carbon dioxide to an epoxide to provide cyclic carbonates or preparation of an amide from the combination of an alcohol and an amine.
Abstract:
A trimetallic catalyst that is a combination of nickel, silver and palladium metal is described. The trimetallic catalyst can be used to produce hydrogen and is useful as a replacement for platinum in hydrogenation reactions.
Abstract:
A composition of matter is provided comprising hierarchically ordered crystalline microporous material having well-defined long-range mesoporous ordering of cubic symmetry. The composition possesses mesopores having walls of crystalline microporous material and a mass of mesostructure between mesopores of crystalline microporous material. Long-range ordering is defined by presence of secondary peaks in an X-ray diffraction (XRD) pattern and/or cubic symmetry observable by microscopy.
