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.

Abstract: The present development is a process to produce commodity chemicals such as methanol and syngas using an integrated plasma catalysis technology. The method comprises providing a fixed or fluidized bed reactor having a microwave plasma flame and a catalyst bed with a catalyst, wherein the catalyst is an alloyed bimetallic nanowire. In the process, the plasma flame fluidizes the catalyst thereby producing a more effective catalyst than the non-fluidized catalyst. It is anticipated that the reactor can have a throughput capacity of up to 30 Lpm/kW and can be effective for the conversion of CO2, CH4, air, water, and combinations thereof, through reactions such as pure CO2 splitting, reverse water gas shift (RWGS) for CO production, methanol synthesis, and plasma reforming of methane, thereby making a system that would be attractive for small GTL units.
