The invention belongs to the technical field of environment-friendly materials, and particularly relates to a method for preparing carbon microspheres by using an alkali / urea aqueous solution low-temperature pretreatment cellulose hydrothermal method. Cellulose is used as a raw material, an alkali / urea solution is used for carrying out dissolution pretreatment on the cellulose under the low-temperature condition to obtain regenerated cellulose gel, then the regenerated cellulose gel is transferred into a reaction kettle for a hydrothermal reaction, and after the reaction kettle is naturally cooled to the room temperature, the obtained hydrothermal solid is washed and dried to prepare the carbon microspheres. According to the method, the crystallinity and polymerization degree of cellulose are effectively reduced, the intensity of the hydrothermal reaction process is improved, and more stable, uniform and smooth hydrothermal carbon microspheres are formed. The method provides a wide prospect for large-scale and sustainable synthesis of the carbon microspheres, and opens up a new way for synthesizing a functional carbon material for efficient utilization of cellulose. The hydrothermal carbon microspheres prepared by the method have the advantages of environmental friendliness, sustainability, low cost and the like.
