Title:
METHOD FOR PRODUCING POROUS CARBON-COATED METAL NANOPARTICLES AND POROUS CARBON-COATED METAL NANOPARTICLES PRODUCED USING SAME
Document Type and Number:
WIPO Patent Application WO/2013/100346
Kind Code:
A1
Abstract:
The present invention relates to a method for producing porous carbon-coated metal nanoparticles, and to porous carbon-coated metal nanoparticles produced using same. More specifically, the present invention comprises: producing a metal precursor solution by dissolving a metal precursor in a carbon-containing solvent (Step 1); producing carbon-containing metal nanoparticles by irradiating the metal precursor solution of Step 1 with ultrasonic waves (Step 2); extracting and drying the carbon-containing metal nanoparticles from the metal precursor solution of Step 2 irradiated with the ultrasonic waves (Step 3); and heat treating the carbon-containing metal nanoparticles of Step 3 at a temperature of between 800°C and 1,200°C (Step 4). According to the method of the present invention, the surfaces of the metal nanoparticles can be coated with carbon in a uniform manner, pores can be formed on the carbon membrane, and therefore, carbon-coated metal nanoparticles having free entrance and exit of ions can be produced in quantity.
