Abstract: The present invention discloses a method for preparing surface-active onion-like carbon nanospheres based on vapor deposition, comprising: directly preparing high-surface-activity onion-like carbon nanospheres formed by coating ferroferric oxide nano-particles on an onion-like graphitized shell by taking liquid small organic molecule alkane n-dodecane as a carbon source to perform chemical vapor deposition at high temperature of 650˜700° C. in an inert carrier gas environment with existence of a ferrocene catalyst. An onion-like carbon nanosphere product prepared according to the present invention has good surface activity and thermal stability, is wide in practicability, and can be widely applied to the fields of adsorbing materials, energy storage materials, catalytic materials, medical materials and the like.
