Abstract
High-angle annular dark-field or Z-contrast microscopy was used to dem onstrate that well dispersed metal supported catalysts consist of nano meter sized clusters. Depending upon the impregnated metal, different cluster sizes were observed. Grouping of Pd clusters could also be con firmed by analytical electron microscopy. (C) 1994 Wiley-Liss, Inc.
