Abstract:
본발명은탄소지지체및 탄소지지체에담지된코어-쉘나노입자를포함하고, 코어-쉘나노입자의코어는이종원소를포함하지않는코발트금속이고, 쉘은탄소를포함하는촉매에관한것이다. 이에의하여, 본발명의산소환원반응용촉매는리간드안정화법과열처리를통해코발트코어-탄소쉘나노입자가탄소지지체에담지된촉매로, 나노크기의입자로높은분산도를갖도록촉매를합성할수 있으며, 특히알칼라인분위기에서구동되는연료전지에서산소환원활성과내구성을향상시킬수 있으며, 이에따라캐소드에전극촉매로적용되어결과적으로연료전지의효율을향상시킬수 있다.
Abstract:
The present invention relates to a method of synthesizing nano-sized metal and alloy nanoparticles by depositing metal and alloy nanoparticles having excellent uniformity of particle size on the surface of powder which is a parental material using a vapor deposition method, and melting the parental material by a solvent or heat, and to a production device thereof. More specifically, as an effective and inexpensive synthesizing method for solving a multiple and high-priced synthesizing method using chemical reduction reaction which is demerits of an existing method, provided are a method of synthesizing highly uniform sized metal, metal supported to alloy catalyst nanoparticles and carbon, and alloy catalyst nanoparticles and a production device thereof.
