What Role Does Quantum Size Effect Play in Selectivity?
The quantum size effect can also influence the selectivity of a catalyst. For example, in the hydrogenation of unsaturated hydrocarbons, the size of palladium nanoparticles can determine whether the reaction favors the formation of alkanes or alkenes. Smaller particles can lead to higher selectivity for alkenes due to changes in the adsorption and desorption properties of the reactants and products.
