Graphitizable carbons have been known to form single-crystal graphite after high-temperature heat treatment up to 3000℃, whose microstructure apparently consists of single carbon layers and shows a large number of fullerene-like nanoparticles. There are a variety of parameters to determine the results of catalytic graphitization, such as preparation methods, particle sizes of catalysts, heat treatment temperatures, and carbon sources. But, most of the processes have a problem of the high-temperature heat treatment. In this study, in order to overcome this issue, we adopted the microwave irradiation (MWI). The catalytic graphitization of phenolic-formaldehyde (PF) resin with ferric nitrate (FN) catalyst was carried out by using MWI. Graphene was obtained from PF resin with FN as a catalyst after MWI process. It is postulated that the natural graphite heated by MWI induced graphitizatioin of PF in the presence of FN as a catalyst. |
