Example SAXS experiment to study the structure of a microporous nongraphitic carbon material. (a) Schematic showing the normal setup of a SAXS instrument. (b) Intensity versus scattering vector curve plot (log–log scale), highlighting morphological (low Q ranges), microstructural (intermediate Q ranges), and structural (large Q ranges) features of the material probed by the technique. (c) Intensity versus scattering angle 2θ plot (linear scale) of the same spectrum, which is normally used for PXRD.
