Summary: The evolution of surface Cr species on Cr2O3/Al2O3 catalysts was investigated by steam pre-treatment, which introduced hydroxyl groups without affecting valence states and aggregated states. The surface structural features of CrOx/Al2O3 catalysts were analyzed, showing that hydroxyl groups were produced and then mostly removed, resulting in abundant oxygen defect sites. These defect sites exhibited a higher number of acidic sites and demonstrated a relatively high PDH activity. This strategy of introducing hydroxyl groups to construct oxygen defect sites is applicable to other oxide materials, providing a novel perspective for catalyst design.
