Title
Highly active gold catalysts loaded on NiAl-oxide derived from layered double hydroxide for aerobic alcohol oxidation
Abstract

•Novel Au catalyst loaded on NiAl-oxide derived from its layered double hydroxide is achieved.•Au/NiAlO-2.5 shows remarkable performance for aerobic oxidation of alcohols.•The enhanced performance is mainly attributed to the synergistic effect between Au and NiAlO-2.5 on reaction mechanism.•The synergistic effect is beneficial to the restore of the active sites of Au.

Highly active aerobic oxidation of alcohols under mild conditions is achieved by using the catalyst constituted of Au nanoparticles supported on mixed NiAl-oxide derived from its corresponding layered double hydroxide. Besides the contribution of electronic interaction, the enhanced catalytic property of the Au catalyst is mainly attributed to the synergistic effect between the Au and the support on reaction mechanism. The unique support with loading Au nanoparticles comes through structural interconversion between the mixed oxide and the layered double hydroxide upon the water exchange during the reaction, which is beneficial to the fast removal of water from the Au surface and then accelerates the restore of the active sites of Au for oxidation of alcohols.
