Intermetallic GaPd 2 Thin Films for Selective Hydrogenation of Acetylene

An Egg-Shell Pd-Ag/ α -Al 2 O 3 Catalyst for Tail-End Acetylene Selective Hydrogenation

Palladium Gallium Intermetallic Compounds for the Selective Hydrogenation of Acetylene Part II: Surface Characterization and Catalytic Performance

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 investigated under diff...

Palladium Gallium Intermetallic Compounds for the Selective Hydrogenation of Acetylene Part I: Preparation and Structural Investigation Under Reaction Conditions

15 August 2008 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 as-prepared materials can be increased by careful mechanical treat...

Selective Hydrogenation of Acetylene over Palladium in Ultra High Vacuum

Under ultra-high-vacuum conditions, precoverage of a palladium(ll1) surface with hydrogen does not affect either the kinetics or the extent of acetylene uptake at 175 K. The subsequent reactive behavior of the system is however radically altered. Benzene formation is strongly suppressed, the transformation of adsorbed acetylene to another species (@-phase) is enhanced, and the yield of ethylene...
