摘要

Metal-dispersed porous carbon was prepared from phenolic or furan resin mixed with Co or Ni naphthenate. The formed metal particles in these metal-dispersed porous carbons are apparently smaller than those in the metal-carbon composite prepared from metal nitrate. In the case of the metal-dispersed porous carbon prepared from phenolic resin and Co naphthenate, graphite phase was formed above 800°C around Co nanoparticles. XRD patterns and TEM micrographs confirm that metal naphthenate works as a metal source from which dispersed nanosize metal particles formed. The porous carbons prepared from phenolic or furan resin with Co or Ni naphthenate have specific surface area of approx. 400 m2/g. For the porous carbon from phenolic resin, mesopore was formed within the sample by cracking or breaking up the large particles. These results indicate that mixing of phenol monomer and the naphthenate before polymerization results in development of mesopore.
