A combined molecular-beam and quantum-simulation study that explores the catalytic behavior of tiny platinum clusters calls into question a well-established precept regarding the influence of structure on the reactivity of solid catalysts (Nat. Commun. 2016, DOI: 10.1038/ncomms10389). Years of experiments have shown that platinum-catalyzed hydrogenation of ethylene to ethane does not depend on the surface structure of the platinum crystallites. This archetypal “structure-insensitive” reaction has long stood in . . .
