Etching of the intermetallic compounds PdGa and Pd3Ga7: An effective way to i…
Abstract. The structurally ordered intermetallic compounds PdGa and Pd3Ga7 constitute highly selective catalysts for the selective semi-hydrogenation of acetylene. The milling of as-synthesized samples, followed by etching with ammonia solution increased the activity of the catalysts by factor of 60. Chemically etched samples possess high activity and simultaneously keep their high selectiv…

Bromine-promoted PtZn is very effective for the chemoselective hydrogenation …
Abstract. The phase pure, unsupported intermetallic compound PtZn is intrinsically active and selective for chemoselective hydrogenation of crotonaldehyde to crotyl alcohol in the absence of any support effects or auxiliary phases. During un-promoted reaction conditions, the PtZn surface becomes platinum enriched within the XPS sampling depth with respect to the 1:1 bulk stoichiometry. Cata…

Palladium–gallium intermetallic compounds for the selective hydrogenation o…
Abstract. The structurally well-defined intermetallic compounds PdGa and Pd3Ga7 constitute suitable catalysts for the selective hydrogenation of acetylene. The surface properties of PdGa and Pd3Ga7 were characterized by X-ray photoelectron spectroscopy, ion scattering spectroscopy and CO chemisorption. Catalytic activity, selectivity and long-term stability of PdGa and Pd3Ga7 were investiga…

Abstract. The intermetallic compounds PdGa and Pd3Ga7 are introduced as selective catalysts for the hydrogenation of acetylene. Single phase PdGa and Pd3Ga7 can readily be prepared by the appropriate thermal treatment of the stoichiometric mixtures of the corresponding elements. The initial low surface areas of the asprepared materials can be increased by careful mechanical treatment withou…
