The bridging hydride species (Zn–H–Zn), commonly formed through H₂ dissociation on ZnO surfaces, are essential for hydrogenating unsaturated hydrocarbons. Here, the authors show that surface hydroxyls on ZnO nanorods can migrate to nearby oxygen vacancies and similarly generate reactive Zn–H–Zn species, which they identify by solid-state NMR spectroscopy as active in CO₂ hydrogenation to methanol.
