ZnO and ZrO, has been produced under basic conditions. Hydrozincite, precipitated from a zinc acetate solution under alkaline conditions (after drying and calcination) transformed to ZnO,. This oxygen-deficient solid only reduced marginally in 5 kPa H, at a maximum rate at 770 K, as confirmed by a Z
## Abstract On the surface: Adsorption of O~2~ at the surface oxygen vacancy (SOV) sites of TiO~2~ reconstructs the lattice oxygen (healing SOVs), resulting in a decrease of the photocatalytic activity of oxidizing CO over vacuumβpretreated TiO~2~ with increasing temperature (see scheme). Adsorptio
