Abstract: "The oxidation of alcohols
to aldehydes with O(2) in place of stoichiometric oxygen donors is a crucial
process for the synthesis of fine chemicals. However, the catalysts that
have been identified so far are relatively inactive with primary alkyl
alcohols. We showed that Au/Pd-TiO(2) catalysts give very high turnover
frequencies (up to 270,000 turnovers per hour) for the oxidation of
alcohols, including primary alkyl alcohols. The addition of Au to Pd
nanocrystals improved the overall selectivity and, using scanning
transmission electron microscopy combined with x-ray photoelectron
spectroscopy, we showed that the Au-Pd nanocrystals were made up of a
Au-rich core with a Pd-rich shell, indicating that the Au electronically
influences the catalytic properties of Pd."
