Stable carbon nanospheres were successfully prepared by means of depositing the soot of the incomplete combustion of mixed aliphatic hydrocarbons. The as-prepared carbon nanospheres were carefully characterized by the field emission scanning electron microscopy and transmission electron microscopy to investigate the structures at micro- and nanometer scale. The method was extremely cheap, facile, time-saving and avoided the use of any special equipment, special reagents and complex process control. The X-ray photoelectron spectroscopy showed the chemical composition of the carbon spheres. The result demonstrates a new method for the preparation of the carbon nanospheres with uniformed 50 nm diameters which are widely used in both fundamental and applied research.
