  • Formation and development of micropores in carbon prepared via catalytic carbonization of phenolic resin containing Fe or Ni compounds

    Language:English   Publishing type:Research paper (scientific journal)  

    The formation and development of micropores in carbon prepared by catalytic carbonization (graphitiza- tion) was investigated. Phenolic resin mixed with ferrocene or nickelocene was carbonized at 1000 °C in Ar. A novel mechanical method that was used for mixing phenolic resin and metallic compound favored formation of micropores in the resulting carbon, compared with conventional homogeneous mixing. Decreasing the catalyst content led to increased micropore surface area. At low catalyst content, catalyst particles were finely dispersed. Small (<10 nm) catalyst particles inhibited the development of stacked structures of carbon aromatic layers in the amorphous component (A-component), which in turn pro- duced accessible micropores. Increasing catalyst content facilitated conversion of A-component into tur- bostratic component (Ts-component) with a partially graphitized structure, which decreased the number of micropores. The formation of Ts-component is related to the formation of mesopores, which progres- sively replaced micropores as the amount of Ts-component increased.

  • Control of mesoporous and crystalline structures in turbostratic carbon derived from Fe- or Ni-doped phenolic resin

    Katsuya Inomata, Yoshinobu Otake

    Language:English   Publishing type:Research paper (scientific journal)  

    A technique to control the mesoporous structure and crystallites present in turbostratic carbon (Ts-carbon) derived from Fe- and Ni-doped phenolic resin is described. To eliminate the effect of heat treatment temperature, all of the Fe- and Ni-doped phenolic resins are carbonized at a fixed temperature of 1000 °C. The catalyst content in the obtained Ts-carbon varies from 0.001 to 5 mmol/g. Mesopores and turbostratic crystallites are formed in the Ts-carbon samples, and these increase in size as the catalyst content and its particle size increases. The turbostratic crystallites assemble to form carbon aggregates with a cup- stacked, thin tube-like, or coil-like structure. The mesopore surface area increases proportionally with the amount of turbostratic crystallites rather than the type of carbon aggre- gate. It is proposed that the mesopore is surrounded by tur- bostratic crystallites. Altering the size of the turbostratic crystallites in Ts-carbon has revealed an effective method for controlling the size and volume of its mesopores.
