The Cover shows that a specific surface atomic arrangement of an ordered alloy governs unprecedented surface stereochemical catalysis; hydrogen‐mediated cis – trans alkene isomerization is selectively catalyzed over orthorhombic Pnma crystals such as RhSb without overhydrogenation to the alkane. In their Full Paper, S. Furukawa et al. describe how exposed facets of intermetallic RhSb nanoparticles display unique surface atomic arrangements. The geometric constraints of the surfaces and steric hindrance from one alkyl group of a cis ‐alkene effectively limit hydrogen diffusion to one direction, enabling reversible one‐atom hydrogenation for isomerization, but inhibiting irreversible two‐atom hydrogenation for overhydrogenation. More details can be found in the Full Paper by S. Furukawa et al. on page 3472 in Issue 21, 2015 (DOI: 10.1002/cctc.201500808).
