Uniform cyclomatrix polyphosphazene spheres with diameter of about 410 nm were firstly synthesized rapidly at room temperature by precipitation polymerization of hexachlorocyclotriphosphazene with 4,4′-sulfonyldiphenol, using triethylamine as acid-acceptor and acetonitrile as solvent. Then, monodisperse carbon spheres with abundant micropores were produced by carbonization of the polyphosphazene spheres at a high temperature under a nitrogen atmosphere. As-produced carbon spheres were well characterized by SEM, TEM, EDX, and N2 adsorption technique. Results show that the carbon spheres possess an average diameter of 320 nm, a BET surface area of about 752 m2·g-1, a total pore volume of 0.55 m3·g-1, and a micropore size distribution.
