Abstract
Gold nanoparticle-loaded, antimony-doped tin oxide nanocrystals (Au/ATO NCs) show thermally activated catalytic activity for the oxidation of cinnamyl alcohol to cinnamaldehyde by hydrogen peroxide. Light irradiation (λex>660 nm, ∼0.5 sun) of Au/ATO NCs gives rise to a more than twofold increase in the rate of reaction with ∼95 % selectivity. Kinetic analyses indicated that the striking enhancement of the reaction stems from the rise in the temperature near the catalyst surface of ∼30 K due to the photothermal effect of the ATO NCs. More information can be found in the Research Article by H. Tada and co-workers (DOI: 10.1002/chem.202201653).
