▎ 摘  要

We report for the first time a facile and efficient strategy to prepare carbon microspheres by the polymerization of glucose in the presence of graphene under hydrothermal carbonization. The morphologies characterizations of the as-synthesized products confirmed that the technique in this paper acted as a good strategy. A great deal of carbon microspheres with good morphology and uniform diameter were prepared. The structure characterizations indicated that there were many functional groups on the surface while the spheres were mostly amorphous structure. A formation mechanism was proposed that involved curved graphene sheets as a substrate for microsphere formation. As this route is low-cost, green and simple, and the experimental parameters are very easy to control, it may provide a great convenience to study properties and applications of carbon microspheres.
