Influence of Carbon Deposition on the Hydrogen Distribution in Pd Nanoparticles and Their Reactivity in Olefin Hydrogenation

摘要

The accumulation of carbonaceous deposits resulting from the early decomposition of the reactants is recognized to considerably affect the activity and the selectivity in hydrocarbon conversions promoted by transition metals.The underlying microscopic mechanisms of carbon-induced changes in reactivity have recently been addressed using the surface science approach for the selective hydrogenation of alkynes and the isomerization and hydrogenation of alkenes.
