摘　　要：在十二烷基三甲基溴化铵(CTAB)的辅助下,利用水热法制备了WO3/ZrO2复合氧化物纳米样品,利用XRD、TEM、SAED、N2吸附-脱附等方法对样品的形貌、结构、孔径进行了表征.结果表明:氧化钨被氧化锆包覆煅烧后,团聚成网状结构的纳米粒子,其BET表面积为368m2/g,平均孔径为5.29nm,孔分布不均匀,无序程度极高.The cetyltrimethylammonium bromide（CTAB） assisted the fabrication WO3/ZrO2 nanocomposite is developed by the hydrothermal method.The morphology,structure and pore diameter are characterized through X-ray diffraction（XRD）,transmission electron microscopy（TEM）,selected area electron diffraction（SEAD） and N2 adsorption-desorption isotherms.The results show that the nanoparticles aggregated with the net-like structure after the calcination of WO3 coated with ZrO2.The BET surface area and averaged pore diameter was calculated to be 368 m2/g and 5.29 nm,respectively.The pore distribution is not uniform with high disordered structure.
