摘　　要：CuO nanoparticle was synthesized via wet chemical method and was characterized diffraction （XRD）, nitrogen adsorption-desorption, and scanning electron microscopy （SEM） by X-ray Catalytic oxidation of cumene with molecular oxygen was studied over CuO nanoparticle. The catalysts showed markedly higher activities as compared to CuO prepared by conventional method, CuO/Al2O3, or homogeneous copper catalyst under comparable reaction conditions. The cumene conversion, cumene hydroperoxide （CHP） yield, and selectivity using 0.25 g CuO nanoparticle catalyst and 0.1 mol cumene at 358 K for 7 h were 44.2%, 41.2% and 93.2%, respectively. The catalyst can be recycled. After 6 recycled experiments, no loss of catalytic activity was observed.CuO nanoparticle was synthesized via wet chemical method and was characterized diffraction （XRD）, nitrogen adsorption-desorption, and scanning electron microscopy （SEM） by X-ray Catalytic oxidation of cumene with molecular oxygen was studied over CuO nanoparticle.
