摘　　要：采用沉积沉淀法制备出Au/TiO_2-SiO_2催化剂,使用X射线衍射(XRD)和透射电子显微镜(TEM)对其进行表征,进一步考察N-羟基邻苯二甲酰亚胺(NHPI)和Au/TiO_2-SiO_2作为催化剂对环己烷氧化性能的影响。结果表明,NHPI与Au/TiO_2-SiO_2质量比为1∶1,在150℃,氧气压力1.5 MPa下反应3 h,环己烷的转化率高到38.0%,酮醇选择性为79.4%。Au/TiO2-SiO2 catalyst was prepared by deposition-precipitation method and characterized with X-raydiffraction （XRD） and transmission electron microscopy （TEM）. The effect of N- hydroxylphthalimide （NHPI）and Au/TiO2-SiO2 as catalysts on oxidation property of cyclohexane was also studied. It was found that cyclohexaneconversion of 38.0% and selectivity to cyclohexanone and cyclohexanol of 79.4% were obtained under the conditionof the mass ratio of the NHPI and Au/TiO2-SiO2 at 1∶1, 150 ℃, reaction for 3 h and 1.5 MPa oxygen pressure.
