Abstract:
Carbon nanospheres (CNSs) with the diameters of 50–250nm were synthesized through a one-step solvothermal method at about 300°C. In this process, benzene and hexachloroethane (C₂Cl₆) served as carbon source for the CNSs. The results showed that the CNSs were composed of a mixture of graphitic nanocrystallites and amorphous carbon. It is believed that they formed through intermolecular Friedel–Crafts alkylation and dehydrogenation reactions in the presence of anhydrous aluminum chloride (AlCl₃). The mechanism of carbonization and the effect of Al particles on the morphology of carbon products are discussed.
