AB  - The metal-organic zeolite imidazolate framework-8 (ZIF-8) supported gold-silver 
      bimetallic catalysts with a core-shell structure (Au@Ag/ZIF-8 and Ag@Au/ZIF-8) 
      and cluster structure (AuAg/ZIF-8) were successfully prepared by the 
      deposition-redispersion method. Energy dispersive X-ray spectroscopy (EDS) 
      elemental mapping images displayed that in the Au@Ag/ZIF-8 catalyst, Ag atoms 
      were deposited on an exposed Au surface, and core-shell structured Au@Ag 
      particles with highly dispersed Ag as the shell were formed. Additionally, the 
      XPS investigation at gold 4f levels and silver 3d levels indicated that the Au 
      and Ag particles of Au@Ag/ZIF-8, Ag@Au/ZIF-8, and AuAg/ZIF-8 were in a zero 
      valence state. Among the resultant catalysts obtained in this study, Ag@Au/ZIF-8 
      catalysts showed the highest catalytic activity for the selective oxidation of 
      benzyl alcohol, followed by AuAg/ZIF-8 and Au@Ag/ZIF-8. The turnover frequency 
      (TOF) values were in the order of Ag@Au/ZIF-8 (28.2 h(-1)) > AuAg/ZIF-8 (25.0 
      h(-1)) > Au@Ag/ZIF-8 (20.0 h(-1)) at 130  degrees C within 1 h under 8 bar O(2) when using 
      THF as solvent. The catalysts of Au@Ag/ZIF-8 and Ag@Au/ZIF-8 with core(-)shell 
      structures have higher benzaldehyde selectivities (53.0% and 53.3%) than the 
      AuAg/ZIF-8 catalyst (35.2%) in the selective oxidation of benzyl alcohol into 
      benzaldehyde. The effect of the solvent, reaction temperature, reaction time, and 
      reaction pressure on benzyl alcohol conversion and benzaldehyde selectivity in 
      benzyl alcohol selective oxidation over Au@Ag/ZIF-8, Ag@Au/ZIF-8, and AuAg/ZIF-8 
      were also investigated. All of the catalysts showed excellent performance at 130 
       degrees C under 8 bar O(2) within 1 h when using THF as the solvent in the selective 
      oxidation of benzyl alcohol to benzaldehyde. Moreover, the catalysts can be 
      easily recycled and used repetitively at least four times.
