“…The particle size distribution of rhodium supported on pumice, an amorphous foam constituted mostly of silica and alumina, has been investigated by Balerna et al [101]. The radius distribution obtained by fitting the experimental SAXS pattern with a scattering curve calculated assuming a log-normal distribution of spherical metal particles is given in Fig.…”
