Abstract

Highly dispersed gold nanoparticles supported on Cu-doped spinel oxides were prepared by a simple deposition-precipitation method. The results indicate that Au/MgCuCr2O4 catalyst is very efficient for gas-phase oxidation of cyclohexanol to cyclohexanone, giving 69.5% and 86.4% yield of cyclohexanone at 260 °C and 300 °C, respectively. Deactivation was not observed in a 100 h stability test. This excellent performance can be correlated with the highly stable gold nanoparticles in the reaction deriving from the strong gold-support interaction and efficient Au–Cu synergy.
