Embodiment 1
[0026] Copper acetate was used as a catalyst to synthesize carbon spheres. Add 1g of copper acetate to a stainless steel reaction kettle, add 30ml of absolute ethanol, cover it, and put it into a temperature-programmed furnace for heating and carbonization. Heat to 500°C at a heating rate of 10°C / min, and react for 10h. Then it was naturally cooled to room temperature, the product was washed with absolute ethanol, soaked in 1:3 hydrochloric acid to remove the catalyst and impurities therein, and then washed with distilled water and absolute ethanol respectively, and the sample was dried in vacuum at 60°C for 4 hours to obtain a black powder. The obtained powder was characterized and analyzed by transmission electron microscope (TEM), scanning electron microscope (SEM) and X-ray diffraction (XRD), and it was confirmed that the obtained product was a high-purity carbon sphere with a content of more than 95%. .

Abstract
A synthesis method for new carbon material is disclosed in this invention. Said method includes in a sealed stainless steel reactor, using nontoxic organic compoud as carbon resource and metal, acetate and metal inorganic salt or metal and metal inorganic salt as catalysts, wherein the carbon resource / catalysts ratio is 10 mL :1 g-100 mL : 1 g, programmed-heating and charring, purifying, and drying to obtain the carbon spheres with a diameter of 1-4 mum. The method has the advantages of simple process, convinent operation, no strict requirement for apparatus, and being easy for mass production.
Description
technical field [0001] The invention belongs to the technical field of carbon materials, and relates to a method for synthesizing carbon spheres by solvent heat, in particular to a method for synthesizing high-purity carbon spheres. Background technique [0002] The discovery of spherical carbon materials was in the 1960s. During the study of the formation of coke, it was found that mesophase transformation would occur during the heat treatment of pitch compounds, and mesophase pellets would be formed. In 1973, Honda and Yamada separated the mesocarbon microbeads from the asphalt matrix, and called the separated micron-scale spherical materials mesocarbon microbeads (MCMB). However, the yield of the method for preparing mesocarbon microspheres is low (generally 5-10%), the extraction process is cumbersome and lengthy, the size of the microspheres cannot be controlled, and the structure is relatively simple. In the preparation of spherical carbon materials, the most mature a...
