Inside Cover: Photocatalytic Aerobic Oxidation of Alcohols on TiO2: The Acceleration Effect of a Brønsted Acid (Angew. Chem. Int. Ed. 43/2010)

The acceleration effect of a Brønsted acid was identified in the photocatalytic oxidation of alcohols using TiO2. In their Communication on page 7976 ff., J. Zhao and co-workers show that the acid adsorbed onto the catalyst surface promotes the decomposition of the Ti/H2O2 species to regenerate active sites for the oxidation.
