摘要:Methods and processes for preparing supported metal catalysts are provided, where the supported metal catalysts can be used for the bulk synthesis of carbon nanotubes. The salts of the metal and the support are selected such that they are soluble in the same solvent. The catalyst can be prepared from the liquid phase through joint precipitation of the metal and the support material. The methods can be used to increase the metal load on the support. Use of the catalysts increases the yield of the carbon nanotubes.

摘要:The present invention provides a novel process for synthesis of a copper-alloy particle with improved grain boundary properties. The process comprises the steps of: forming a solution from an alcoholic agent and a branched dispersing agent; forming a reaction mixture with the solution and a copper precursor and optionally a nickel precursor; heating the reaction mixture; cooling the reaction mixture; adding an additional amount of copper precursor and at least one precursor selected from the group consisting of: nickel, zinc, and bismuth; heating the reaction mixture; and maintaining the reaction mixture for a time sufficient to reduce the reaction mixture to copper-alloy particles.

摘要:At the time of synthesis of lithium nickelate, by adding a firing aid to material to be fired, crystal growth is promoted at a temperature that is lower than a firing temperature necessary for obtaining desired crystal growth of lithium nickelate, and substitution of elements that contribute to structural stability in crystals is promoted. Furthermore, distortion of crystal or loss of oxygen at the time of synthesis is suppressed. Thus, a lithium ion secondary battery having excellent charge and discharge characteristics and cycling characteristics can be provided.

摘要:A method for the synthesis of nanocomposites is provided. The method comprises the steps of mixing carbon nanotubes with a urea solution to form urea/carbon nanotube composites (first step), mixing the urea/carbon nanotube composites with a solution of a metal oxide or hydroxide precursor to prepare a precursor solution (second step), and hydrolyzing the urea in the precursor solution to form a metal oxide or hydroxide coating on the carbon nanotubes (third step). Further provided are nanocomposites synthesized by the method. In the nanocomposites, a metal oxide or hydroxide is coated to a uniform thickness in the nanometer range on porous carbon nanotubes. Advantageously, the thickness of the coating can be easily regulated by controlling the urea content of urea/carbon nanotube composites as precursors. In addition, the nanocomposites are nanometer-sized powders and have high electrical conductivity and large specific surface area. Therefore, the nanocomposites are useful as electrode active materials for electrochemical capacitors, including pseudo capacitors and electrochemical double layer capacitors, lithium secondary batteries, and polymer batteries. Further provided is a capacitor comprising the nanocomposites.
