Carbon framework formed in narrow pores of zeolites retained
to templated carbon particles exhibited the morphology of the zeolite
template particles. On the basis of this concept, there were few
studies on the carbon formation in the zeolite nanoscale pores. Poly
furfuryl alcoholand polyacrylonitrile was carbonized in the zeolite
channels and then the resultant carbon was obtained by washing with
HF. In addition to zeolite frames, mesoporous silica molecular
sieves, were also used.
