The X-ray diffraction study of three-dimensional disordered network of nanographites: Experiment and theory

The average sizes of nanographites (the structure units of activated carbon fibers) have been determined by fitting experimental X-ray diffraction profile by theoretical curves, calculated using Warren-Bodenstein equations. The structure parameters of nanographites obtained by this way are different from ones determined by standard Scherrer equation. The result indicates that the shape factor of the Scherrer equation for the considered ensemble of nanographites differs from generally accepted value
