| titleOfInvention | Method for synthesizing core-shell structure carbon-coated gold nanoparticles with regular spherical morphology |
| abstract | A method for synthesizing core-shell structure carbon-coated gold nanoparticles with regular spherical morphology. The invention belongs to the field of inorganic materials, and particularly relates to a synthetic method of inorganic materials. The invention provides a method for synthesizing core-shell structure carbon-coated gold nanoparticles with regular spherical morphology, and the method can adjust the size of the core-gold nanoparticles and the thickness of a shell layer-resin layer according to actual needs, thereby providing wide space for subsequent application. The product is as follows: the alloy is prepared from a gold source, a reducing agent sodium borohydride, benzenediol and formaldehyde solution as carbon sources, ammonia water, ethanol and water. The method comprises the following steps: adding a gold source and a reducing agent into the water phase, then mixing the gold nanoparticles with a carbon source, then adding absolute ethyl alcohol and ammonia water, reacting at room temperature, then centrifugally separating and drying, and roasting under an inert atmosphere to obtain the spherical carbon-coated gold nanoparticles with the core-shell structure. The carbon-coated gold nanoparticle with the spherical core-shell structure synthesized by the method has better spherical appearance and monodispersity, and the particle size can be controllably adjusted between 50 nm and 250 nm. |
