Chinese patent 200610037096.4 discloses that metal, ethanolate, metal inorganic salt are used as catalysts, cyclohexane, absolute ethanol, isopropanol or polyethylene glycol 600 are used as carbon sources, and carbon spheres are prepared at 500°C-650°C. According to SEM observation, the diameter of carbon spheres is distributed in the range of 1-4 μm. The reaction uses organic solvents, which are toxic and unfriendly to the environment. In addition, the carbonization temperature is too high, which wastes energy.

Abstract
The invention relates to the field of novel carbon material preparation, in particular to a preparation method of one-step synthesis carbon ball. The preparation method comprises the following steps in particular: adding 0.5-2.0 mol / l of sucrose or cyclodextrin solution into a polyfluortetraethylene lining; carrying out reaction for 10-20 hours at a temperature of 120-200 DEG C after the lining is sealed and positioned in a reaction kettle; and carrying out natural cooling to the room temperature, filtering and drying so as to obtain carbon grains with grain diameters of 0.5-2 microns. The invention has simple synthesizing method, convenient operation and environmental-friendly and cheap raw materials, does not have high demand for needed apparatuses and is easy to realize large-scale andindustrial production.
Description
technical field [0001] The invention relates to the field of preparation of novel carbon materials, in particular to a preparation method for synthesizing carbon spheres in one step. Background technique [0002] In recent years, advanced carbon materials represented by graphene and carbon nanotubes have triggered an upsurge of research on carbon materials internationally. Many carbon materials with different shapes, novel structures and unique properties, such as carbon fibers, fullerenes, and nano-carbon spheres, have been researched and developed successively, and have broad application prospects in the fields of electronics, energy, medicine, and materials. [0003] The emergence of spherical carbon materials has aroused great interest in the chemical, material science and business circles, and is considered to be a new type of special material with broad application prospects. Its appearance is a regular spherical shape, and the particle size can be at the nanometer le...
