Abstract

A series of porous carbon materials, produced by pyrolysis of saccharose and anthracene and heat-treated at 1000degreesC, 1900degreesC and 2300degreesC have been studied by wide-angle X-ray scattering. The X-ray data were collected at European Synchrotron Radiation Facility (ESRF) in Grenoble on the ID15 beam line (high-energy X-ray diffraction) using the wavelength lambda=0, 1067Angstrom (E=116,2 keV). The data were recorded in the scattering-vector range from 0.5 to 24Angstrom(-1) which allowed to conversion to real space via the Fourier transform yielding the radial distribution function of a good quality. Analysis of the experimental radial distribution function shows that carbons produced from anthracene transforms into graphite at 1900degreesC and this process is almost complete at 2300degreesC. The saccharose-based carbons remain disordered even at high temperature.
