ABSTRACT:
The present invention discloses a novel use of a catalyst with core-porous shell structure, which includes carrying out an oxidation of an alcohol in vapor phase and in the presence of the catalyst with core-porous shell structure to form an aldehyde or ketone, wherein the catalyst with core-porous shell structure is constituted of a core material and a porous shell material. The core material is a metal having a catalytic activity, and the shell material is a porous inorganic oxide.
