| 摘要: |
Uniform small onion-like carbon (OLC) modified with molybdenum carbide has been synthesized by a one-step process, using detonation-assisted chemical vapor deposition.The obtained material was characterized by transmission electron microscope, energy-dispersive X-ray spectroscopy,Raman spectroscopy, and X-ray diffraction. The results show that the OLC have almost perfect onion structures containing about 7–10 closed shells and exhibit a narrow distribution of 4–6 nm when the C/Mo ratio is about 150. The hexagonal molybdenum carbide (Mo2C) is dispersed on the surface of OLC. The size of OLC can be controlled by adjusting the C/Mo ratios. The formation mechanism of the nanocomposites of OLC and Mo2C is briefly discussed. |
