Descripción
Partial hydrogenation of alkynes has industrial and academic relevance on a large scale, especially those with high selectivities. To increase the activity, selectivity and lifetime of low-loaded Pd monometallic catalyst, the development of bimetallic systems has been investigated. In this work Pd mono (Pd/A) and bimetallic catalysts (PdNi/A and WPd/A) supported on γ-alumina with low metal content are prepared and evaluated during the partial hydrogenation of 3-hexyne at mild conditions. XPS, XRD, TPR and hydrogen chemisorption techniques are used for the characterization, suggesting different kind of Pd species on the mono and bimetallic catalysts. Furthermore, XPS results indicate the presence of electron rich and electron-deficient palladium species (Pd δ- and Pd n+, with δ close to 0 and 0 < n < 2, respectively), electron-deficient species of nickel (Ni n+, with n close to 2) and of W ρ+ (with ρ < 6) on the surface of the bimetallic systems. The Lindlar commercial catalyst, commonly used in these types of reactions is used for comparative purposes. Bimetallic catalysts showed higher activities and very similar selectivities (>93%) than the monometallic system and further than the Lindlar catalyst. The rank of activity order is: WPd/A > PdNi/A > Pd/A Lindlar.
