Abstract:
PURPOSE: A double metal - carbon nanotube, a hybrid catalyst and a manufacturing method thereof are provided to improve hydrogen generation efficiency in comparison with the same mass of the double metal - carbon nanotube hybrid catalyst by remarkably improving catalyst activity property. CONSTITUTION: The double metal - carbon nanotube hybrid catalyst comprises more than 2 kind of transition metals selected from a group consisting of Mn, Ni, Cu, Mo, Tc, Ru, Rh, Pd, Ag, Re, Os, Ir or Pt. The hydrogen can be occurred from the ammonia borane(NH3BH3) aqueous solution because the solution is distributed in the carbon nanotube in which the nitrogen is contained. A manufacturing method of the double metal - carbon nanotube hybrid catalyst comprises a step for manufacturing a carbon nanotube solution by adding the carbon nanotube in a polyoll solution, a step for reducing the carbon nanotube with sodium borohydride, and a step for manufacturing the double metal - carbon nanotube hybrid catalyst capable of making hydrogen from an ammonia borane aqueous solution.

PURPOSE: An arraying method of a nanosubstance using a solution evaporation method is provided to rapidly and easily array the nanosubstance to the desired shape and size by synthesizing a nano-material containing solution and evaporating it. CONSTITUTION: An arraying method of a nanosubstance using a solution evaporation method comprises the following steps: forming a nano-material containing solution by coating a nano-material with a polymer and dispersing the nano-material into a solvent; and arraying the nanosubstance by pouring the nano-material containing solution to a substrate and drying. The coating method of the nano-material with the polymer comprises the following steps: dispersing the nano-material into 1,5-pentanediol; adding a polymer selected from PVP, polystyrene, poly(vinyl acetate), and polyisobutylene; firstly heating at 150~230 deg C for 1~3 hours; and secondly heating at 250~300 deg C for 30 minutes~1 hour.
