Abstract

Nanoscopic observation of mesoporous carbons prepared by catalytic carbonization of Fe- and Ni-containing phenol formaldehyde resins, were studied. Fe- and Ni-catalyzed carbons were prepared under a certain carbonizing condition, then mesopore and nanoscopic morphology of carbon nanotextures were characterized by three different techniques. Designated amounts of ferrocene and nickel nitrate hexahydrate were dissolved separately in methanol and added into resol-type phenol formaldehyde resin. These resins are then thermoset at 80°C, and the resin blocks thus hardened were heat-treated in flowing Ar at 5°C/min up to 1,000°C. SEM and TEM were used, respectively, to observe the nanoscopic morphology and nanotexture of the three types of carbon specimens. These observations reveal cross-sectional morphology and nanotexture inside the carbons. The SEM images indicate that a surface of FePF is covered entirely by whiskers with a relatively uniform diameter of ca 60-70 nm.
