摘　　要：采用一种简单的一步合成法制备出具有新颖的橄榄型纳米氧化铜材料，采用XRD、TEM、氮气吸附等方法对其结构进行表征。结果表明，所合成的纳米氧化铜结构是由微小的纳米晶粒组合成的空心结构，具有较高的比表面积。还考察了合成的纳米氧化铜对苯酚和环己烷的催化氧化活性。A new kind of CuO nanomaterial with olivary morphology was prepared by a simple one-step method. The synthesized CuO nanomaterial was characterized by XRD, TEM and N2 adsorption methods. The synthesized CuO nanomaterial was composed of nanocrystal assembly, presenting hollow structure with high surface area. The catalytic activity of the synthesized CuO nanomaterial was also investigated by catalytic oxidation of phenol and cyclohexane with H2O2.
