Title: Selectivity Control on Hydrogenation reactions through End-On Adsorption of Reactants in Zeolite-Encapsulated Platinum Nanoparticles
Abstract: 
Platinum nanoparticles encapsulated into zeolite Y (Pt@Y catalyst) exhibit excellent catalytic selectivity in hydrogenation of reactant with more than one reducible group in one molecule to the corresponding desired product. The role of zeolite encapsulation toward perfect selectivity can be attributed to constraint of the substrate adsorbed on the platinum surface in an end-on conformation. This conformation results in the activation of only one adsorbed group, with little influence on the other one in the molecule. Owing to a much lower apparent activation energy of Pt@Y for the hydrogenation of a separately adsorbed required to be reacted group than that of the adsorbed unrequired to be reacted group, thus Pt@Y catalyst showing amazing catalytic selectivities in various hydrogenation reactions, including hydrogenation of substituted nitroarenes, aromatic ketone, 5‑hydroxymethylfurfural, and so on.
