Hydrogen activation and spillover … renders the semi‐hydrogenation of acetylene over sub‐1 nm Pd nanoclusters confined within sodalite (SOD) zeolite (Pd@SOD) remarkably selective. In their Communication on page 7668 ff., R. Mu, J. Gong, and co‐workers show that H 2 is dissociated on the Pd nanoclusters inside SOD to form hydrogen species that spill over the SOD surface. The utilization of the small‐pore zeolite SOD was crucial as it only allows H 2 diffusion into the channels and thus prevents over‐hydrogenation to ethane.
