Abstract:
Reaction induced Pd Bi /SiC catalysts exhibit excellent catalytic activity (92% conversion of benzyl alcohol and 98% selectivity of benzyl aldehyde) and stability (time on stream of 200 h) in the gas phase oxidation of alcohols at a low temperature of 240 °C due to the formation of Pd0-Bi2O3 species. TEM indicates that the agglomeration of the 5.8 nm nanoparticles is inhibited under the reaction conditions. The transformation from inactive PdO-Bi2O3 to active Pd0-Bi2O3 under the reaction conditions is confirmed elaborately by XRD and XPS.

Oxidation of Alcohols
The process of oxidation in a chemical reaction is observed in any of the three forms:
Radical Oxidation of Allylic and Benzylic Alcohols
Reactions of Aldehydes and Ketones: Baeyer–Villiger Oxidation
The carbonyl center is...
Oxidation of Alkenes: Syn Dihydroxylation with Osmium Tetraoxide
Hydroboration-Oxidation of Alkenes
Alkynes to Aldehydes and Ketones: Hydroboration-Oxidation
One of the convenient methods for the preparation of aldehydes and ketones is via hydration of alkynes. Hydroboration-oxidation of alkynes is an indirect hydration reaction in which an alkyne is treated with borane followed by oxidation with alkaline peroxide to form an enol that rapidly converts into an aldehyde or a ketone. Terminal alkynes form aldehydes, whereas internal alkynes give ketones as the final product.
