Up to speed : Brønsted acids adsorbed onto TiO 2 dramatically accelerated the photocatalytic oxidation of alcohols without any loss of selectivity (see scheme). This effect results from the decomposition of the Ti species, having a side‐on peroxide, on the TiO 2 surface. The decomposition is aided by the Brønsted acid, thereby regenerating the active Ti sites on the surface of the catalyst.
