High‐angle annular dark‐field or Z‐contrast microscopy was used to demonstrate that well dispersed metal supported catalysts consist of nanometer sized clusters. Depending upon the impregnated metal, different cluster sizes were observed. Grouping of Pd clusters could also be confirmed by analytical electron microscopy. © 1994 Wiley‐Liss, Inc.
