Carbon wool ball material and its preparation method and uses

The present invention relates to a carbon material and Pompon preparation and use. The material includes a core carbon material, carbon fibers, and the one-dimensional growth on the surface thereof. The average particle diameter of the core carbon material is 100nm ~ 1mm, the diameter of the one-dimensional carbon fiber is 1 ~ 500nm, a length of 10nm ~ 100μm. The carbon / carbon composite material is prepared by a chemical vapor deposition method, comprising: preparing metallic iron, cobalt, nickel or molybdenum salt of an alcohol solution of the catalyst; core carbon material is added; pretreatment procedures and warmed to a target temperature, chemical vapor deposition; the product was obtained after purification of the product. Pompon the carbon material having both a stable structure, and having a large specific surface area, which have various uses, can be used as a negative electrode material for lithium ion batteries, as a carrier of the direct methanol fuel cell catalyst, as a dye-sensitized the solar cell electrode material or as a carrier supported catalyst and the like.
