Abstract Carbonnanotubes (CNTs) were in-situ formed via catalytic pyrolysis of phenol resin using nickel nitrate and nickel acetate as the catalyst precursor in the N₂ atmosphere, respectively. The effect of the nickel sources on the morphology and structure of CNTs and the crystallization degree of pyrolytic products were investigated. The graphitization degree of pyrolytic products and the structure of CNTs were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscope (TEM). Results showed that the length to diameter ratio of CNTs and the graphitization degree of pyrolytic products of phenolic resin containing nickel nitrate were higher than that containing nitrate acetate. The dispersion of the two nickel sources in phenolic resin is the main effect reason for the different formation of CNTs.

Key words： phenolic resin nickel sources catalytic in-situ formation carbon nanotubes (CNTs)
