Pd ₂₄ Cu ₁₂ Cages with Open Tripalladium Nodes for Selective Hydrogenation

units. Such a rigid framework, together with the electronic communication among the metal centers, accounts for the exceptional thermal and aerobic stability of the cage. Notably, the cage showcases high catalytic activity and selectivity in the hydrogenation of azobenzene. These findings not only introduce a class of catalytically active palladium nodes for the assembly of chemically different palladium-organic cages but also pave the way for further exploration of cage-based catalysts in hydrogenation processes.
