20080245184 | Preparation method of metal nano particle using micro mixer - Disclosed is a method for preparing metal nanoparticles, the method comprising the steps of: providing a solution of metal salt and a solution of a strong reducing agent with a standard reduction potential of −0.23V or lower; and mixing the solutions by using a micro mixer without supplying additional heat energy from the exterior, while carrying out reduction of the metal. Metal nanoparticles obtained by the above method, and a micro mixer for preparing the metal nanoparticles are also disclosed. The method for preparing metal nanoparticles via the reduction of metal ions in a solution uses a strong reducing agent and a micro mixer. Therefore, it is possible to obtain metal nanoparticles having a particle size of 20 nm or more and a uniform shape and dimension without supplying additional heat energy from the exterior. Additionally, the method is amenable to a continuous process, and thus ensures cost-efficiency and stable product quality required for mass production. | 10-09-2008 |
