Oxygen transport: Here, the authors present the elucidation of the NO decomposition activity of Cu‐ZSM‐5 (see picture) by identifying the bis(μ‐oxo)dicopper species as the key intermediate that allows the smooth formation and desorption of O 2 . Its isomerized (μ‐η 2 :η 2 ‐peroxo)dicopper core is present in natural enzymes, where it is responsible for dioxygen transport and selective oxidation catalysis, similar to the catalytic roles played by Cu‐ZSM‐5.
