Reaction induced robust Pd(x)Bi(y)/SiC catalyst for the gas phase oxidation of monopolistic alcohols

Reaction induced Pd(x)Bi(y)/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 Pd(0)–Bi(2)O(...

Descripción
Sumario:Reaction induced Pd(x)Bi(y)/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 Pd(0)–Bi(2)O(3) species. TEM indicates that the agglomeration of the 5.8 nm nanoparticles is inhibited under the reaction conditions. The transformation from inactive PdO–Bi(2)O(3) to active Pd(0)–Bi(2)O(3) under the reaction conditions is confirmed elaborately by XRD and XPS.
