Abstract: A method of manufacturing a mixed metal oxide powder is provided. The method includes steps of mixing two or more metal precursors in a solvent to form a dispersion of the metal precursors in the solvent; drying the dispersion to obtain a dried mixed metal precursor powder; jet milling the dried mixed metal precursor powder to obtain particles having a size distribution in a range of 0.2-20 micrometers; and exposing the particles to a hydrocarbon flame or oxygen plasma to provide the mixed metal oxide powder. Mixed metal oxide powders produced by the disclosed methods are also provided.

Abstract: The present development is a process for the preparation of nanowire synthesis, coatings and uses thereof. Lithium titanate (LTO) nanowires are synthesized using a continuous hydrocarbon/plasma flame process technology combined with the dry impregnation method. The resulting LTO nanowires can be used as electro active anode materials for lithium ion batteries. The coating parameters, such as thickness, porosity of the film, packing density, and viscosity are controlled using the length of the nanowires, calendaring pressure, and slurry composition.

Abstract: A nanowire catalyst is provided. The catalyst has the formula AxC1-xOd, wherein A is a transition metal or precious metal and wherein C is selected from the group consisting of silicon, aluminum, titanium, zinc, and manganese. Methods for preparing the nanowire catalyst include steps of mixing a binary oxide nanowire powder having element C with a precursor of element A to form a mixture; drying the mixture; and calcining the mixture to provide the nanowire catalyst. The catalyst may be used in methods of dry methane reforming, including bi-reforming and tri-reforming of methane.
