在水热合成复合二氧化硅空心球（HHSS）基础上,以硝酸铜为原料,采用超声辅助浸渍法制备出高分散CuO@HHSS复合催化剂。采用X射线衍射（XRD）、氮气吸附-脱附、X射线光电子能谱（XPS）、扫描电子显微镜（SEM）、透射电子显微镜（TEM）等表征手段对合成催化剂的形貌和结构进行了表征。结果表明：CuO@HHSS催化剂依然保持HHSS的层次纳米中空结构;CuO颗粒高度分散在HHSS表面,而且复合催化剂具有较高的比表面积（488.9 m2/g）。以对硝基苯酚（4-NP）的催化还原反应作为反应模型,考察了CuO和CuO@HHSS催化剂对4-NP还原的催化性能。结果表明：在不同对硝基苯酚浓度下CuO@HHSS展现出优异的催化性能,在200 s内催化硼氢化钠（NaBH4）将4-NP转化为对氨基苯酚（4-AP）。

On the basis of preparing hollow silica sphere（HHSS） by hydrothermal method,CuO@HHSS composite catalysts were prepared with copper nitrate as raw material by ultrasonic assisted-impregnation method.The morphology and structure of the prepared catalyst were characterized by means of X-ray diffraction（XRD）,nitrogen adsorption and desorption,X-ray photoelectron spectroscopy（XPS）,scanning electron microscopy（SEM） and transmission electron microscopy（TEM） etc..Results showed that the CuO@HHSS catalyst still maintained the hierarchical nano hollow structure of HHSS.CuO particles were highly dispersed on the HHSS surface,which showed a high specific surface area（488.9 m2/g）.The catalytic reduction reaction of p-nitrophenol（4-NP） was used as a model reaction to investigate the catalytic performance of CuO and CuO@HHSS catalysts for reduction of 4-NP.The results revealed that CuO@HHSS had excellent catalytic performance at different 4-NP concentrations and catalyze NaBH4 to convert 4-NP to p-aminophenol（4-AP） within 200 s.
