摘要：
Au/SiO2 catalysts were prepared by self-assembly technique and characterized by EDS, XRD, XPS, AAS and N2 adsorption/desorption. They were found to be very efficient catalysts for the selective oxidation of cyclohexane with air in the absence of any solvent or promoter. The influences of Au loading, reaction temperature, reaction pressure and reaction time on the catalytic activity were explored in detail. Under suitable reaction conditions, the conversion of cyclohexane and total selectivity of cyclohexanone and cyclohexanol were up to ~10 and ~92%, respectively.
