Abstract: Understanding the nature of active sites in heterogeneous catalysts and how to create them purposefully opens up the possibility of tailored catalyst design. Here we report mixed-valence subnanometre CoOx clusters, consisting of a few metallic Co<sup>0</sup> atoms on top of Co<sup>2+</sup>, bound to a silicalite-1 support through lattice oxygen atoms as active species for non-oxidative propane dehydrogenation (PDH) to propene. Compared with commercial-like PtSn/Al<sub>2</sub>O<sub>3</sub> and K-CrOx/Al<sub>2</sub>O<sub>3</sub> catalysts also tested in the present study, as well as other state-of-the-art Pt- or Co-containing PDH catalysts, this system showed high on-stream stability, propene productivity and selectivity at close-to-equilibrium propane conversion. Moreover, it showed durability in a series of PDH/regeneration cycles between 500 and 550 °C. The performance of this catalyst system is industrially attractive in terms of propene production costs, as suggested by our initial techno-economic assessment.
