Phenylacetylene semihydrogenation over a palladium pyrazolate hydrogen-bonded network
2021, Inorganica Chimica ActaActivity and selectivity of carbon supported palladium catalysts prepared from bis(Η<sup>3</sup>-allyl)palladium complexes in phenylacetylene hydrogenation
2018, Catalysis CommunicationsCitation Excerpt :It was the case in our previous work too [5]. In some other works, a constant catalyst activity establishes not at once, as in our case, but during next hydrogenation runs [34]. Carbon-supported palladium catalysts containing 9.1 wt% of Pd synthesized by reduction of bis(η3-allyl)palladium complexes as precursors with hydrogen demonstrated good figures in selective liquid-phase hydrogenation of PA to ST. Their performance obeys direct specific surface area effect: the more Pd specific surface area the greater their activity and selectivity.

2015, Chemical Engineering ScienceCitation Excerpt :Table 3 summarizes the activation energies available in the literature. Our activation energies for the two consecutive steps (E1 and E2) are higher than those reported in most previous studies (Aramendía et al., 1990; Jackson and Shaw, 1996; Wilhite et al., 2002; Hardacre et al., 2006), but very similar to those obtained by Chaudhari et al. (1986). This is probably due to the fact that most previously reported data were influenced by mass transfer limitations.
Surface dynamics of the intermetallic catalyst Pd<inf>2</inf>Ga, Part II - Reactivity and stability in liquid-phase hydrogenation of phenylacetylene
2014, Journal of CatalysisCitation Excerpt :It is 0.58 for pure Pd powder, meaning that double bond hydrogenation occurs clearly faster than triple bond hydrogenation. This is typically for Pd catalysts, e.g., in the gas-phase hydrogenation of acetylene [37] and was also reported for the liquid-phase hydrogenation of phenylacetylene [38]. The ability to form hydrides makes Pd highly reactive toward alkene hydrogenation [39].
