Aim of the paper is to apply a modified version of the Rietveld method to t
wo Au-Pd/C catalysts prepared by successive impregnation and reduced in sit
u by a special holder in order to show that a suitable WAXS analysis, perfo
rmed in routine lab and using an X-ray conventional generator, can be very
detailed and rich of information especially when a bimetallic catalyst has
to be considered.
