标题 :Synthesis of ZSM-5 crystals with improved morphology

摘要:Methods are provided for synthesizing crystals having a ZSM-5 framework structure from synthesis mixtures suitable for synthesis of ZSM-12 framework structure crystals in the absence of seed crystals with a ZSM-5 framework structure, such as in the absence of any seed crystals. For synthesis mixtures with a sufficiently high XO 2 :Y 2 O 3 ratio, seeding a synthesis mixture with ZSM-5 seed crystals can result in production of pure phase ZSM-5 crystals with a new morphology. The morphology can include rod-like primary crystallites with a length of about 0.5 μm or less that are organized/aggregated into larger secondary crystal structures. The aggregation of the primary crystallites into a secondary crystal structure can allow for an unexpectedly large mesoporous surface area for the ZSM-5 crystals.

摘要: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.

标题 :Solvent-free synthesis of lanthanide oxide and mixed lanthanide oxide nanoparticles

权利人:NAT TECH & ENG SOLUTIONS SANDIA LLC
摘要:Lanthanide oxides and mixed lanthanide oxides can be produced using furnace or microwave assisted solid-state synthesis. The use of Ln-tri(methylsilyl)amide-based precursors yields spherical nanoparticles. The formation of spherical shaped nanoparticles is likely due to the preferential single-step decomposition of the Ln-TMS as well as the low activation energy to overcome decomposition. Reaction temperature, initial metal ion ratio, and reaction dwell time can be used to control the final nanoparticle size. The method enables solvent-free, high-yield synthesis of morphology-controlled lanthanide oxides.

摘要:A method for a synthesis of a metal catalyst, including providing at least one metal complex including a metal ion and a non-chelating complexing agent having carbon, the complex having a decomposition temperature, and performing a pyrolysis of the complex at a temperature greater than or equal to a decomposition temperature of the complex, whereby inducing a formation of nanoparticles surrounded by a carbon matrix to form the catalyst. Thanks to the carbon matrix, the catalysts provided herein can be corrosion resistant, self-healing, more cost-effective, and can have higher catalytic activity. The synthesis of the catalyst and its properties can furthermore be improved compared to catalysts formed from a complex including a chelating.
