The cover picture shows the transformation of a commercially available supported palladium catalyst (Pd/C) into supported particles of the intermetallic compound GaPd 2 . GaPd 2 as well as GaPd can be obtained by controlled solid‐gas phase reaction, opening a new path to the synthesis of finely dispersed, small and supported intermetallic materials. The basis for the optimized synthesis is formed by thermodynamic data, i.e. the phase diagram, as well as chemical vapor deposition experiments, by which large crystals of GaPd 2 can be obtained. The supported materials show very promising catalytic properties, e.g. in the semi‐hydrogenation of acetylene. Synthesis of supported materials allows to obtain high‐performance materials which combine the excellent catalytic selectivity of unsupported bulk intermetallic compounds with high activity, thus easing industrial application.
