20080241054 | Method for making metal oxide nanocrystal - A method for making the metal oxide includes the following steps: mixing a metal nitrate with a solvent of octadecyl amine, and achieving a mixture; agitating and reacting the mixture at a reaction temperature for a reaction period; cooling the mixture to a cooling temperature, and achieving a deposit; and washing the deposit with an organic solvent, drying the deposit at a drying temperature and achieving a metal oxide nanocrystal. The present method for making a metal oxide nanocrystal is economical and timesaving, and has a low toxicity associated therewith. Thus, the method is suitable for industrial mass production. The metal oxide nanocrystal material made by the present method has a readily controllable size, a narrow size distribution, and good crystallinity | 10-02-2008 |
20100278721 | Method for making mesoporous material - A method for making the mesoporous material includes the following steps: dissolving a nanocrystal powder in an organic solvent, and achieving a solution A with concentration of 1-30 mg/ml; dissolving a surfactant in water, and achieving a solution B with an approximate concentration of 0.002-0.05 mol/ml; mixing the solution A and the solution B in a volume ratio of 1: (5-30), and achieving a mixture; stirring and emulsifying the mixture, until an emulsion C is achieved; removing the organic solvent from the emulsion C, and achieving a deposit; washing the deposit with deionized water, and achieving a colloid; and drying and calcining the colloid, and eventually achieving a mesoporous material.
