概要 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.
