The carbon spheres with uniform particle size were prepared from glucose by hydrothermal method .The effect of glucose concentration ,reaction time ,reaction temperature ,pH value and formal‐dehyde content on the morphology and particle size of carbm spheres was investigated .The morpholo‐gy and structure of carbon spheres were characterized by means of SEM ,FTIR and XRD .The results show that the optimized formula for the preparation of monodisperse carbon spheres is reaction tem‐perature at 160 ℃ ,reaction time at 6 h ,glucose concentration at 0 .25 mol/L ,pH value at 8 and form‐aldehyde content at 2 g .The monodisperse carbon spheres can be produced with a particle size of about 350 nm ,a dispersion coefficient of 0 .011 and a yield of about 20% .T he surface of carbon spheres con‐tains such functional groups as —OH ,—C O and COOH ,and there exists amorphous carbon in the carbon sphere .
