Carbon nanoparticles were prepared by simple method. TEM image shows that the particle size is several nanometers. Furthermore, the specific surface area of the material is reached for 425.8 m2/g. It is much larger than that of carbonVulcan-XC72, which they is widely used as catalyst supports for DMFC electrodes. Carbon nanoparticles is a kind of promising material used for catalyst support in DMFC.
