It has been proposed to use new masking liquids with a relatively low X-ray radiation absorption for SAXS study of complex materials. In presentation will be discussed prospects and restrictions of new technique, examples of their application to study some catalysts and porous composites. Using these liquids we achieved very good agreement between the SAXS and TEM data. The SAXS technique employing such masking liquids can be used as a quick analytical method for determining the particle size distributions of supported metals. Fluorocarbon liquids can eliminate the scattering signal from any support with the density of 2.8 g/cm3 or less.
