▎ 摘　　要

NOVELTY - The method involves (a) putting the metal raw material into the high-temperature evaporator and heating to evaporate, (b) sending the carbon dioxide gas and the raw material steam to the particle forming controller through the carrier gas, (c) making the carbon in the carbon oxide gas react and depositing on the surface of the metal particle during the nucleation and growth process to form sheet-like graphene, (d) importing the raw material into a cooler for cooling and separating the sheet-like graphene from the surface of the formed metal particles, and (e) collecting the graphene-doped ultrafine metal powder. The carbon oxide gas is a mixed gas of carbon monoxide and carbon dioxide. The metal raw material is a kind of transition metal element. The carrier gas is one of the inert gases. USE - Preparation method of graphene-doped metal powder (claimed) based on evaporation and condensation method used for preparation of conductive paste and electrodes in many fields such as new energy batteries, catalysis, and gas storage and energy storage applications. ADVANTAGE - The method can produce graphene powder of lamellar particles on a large scale. The production process is less and relatively simple, the economic benefit is relatively high, the safety is high, and the cost is relatively low. The method has the good technical effect of realizing the co-production and large-scale production of ultra-fine metal powder and flaky graphene, and has excellent production capacity benefit. The particle size of the graphene-doped metal powder fully meets the needs of being applied to conductive paste and electrode preparation. The graphene-doped metal powder has good electrical conductivity, can be well applied to the preparation of conductive paste and electrodes, has relatively low cost. The method realizes the co-production of ultrafine metal powder and lamellar graphene and the large-scale production of graphene powder of lamellar particles. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a graphene-doped metal powder.
