首次以不同孔道结构的介孔氧化硅薄膜为模板,采用电化学沉积的方法,合成了金属铜和半导体氧化锌的纳米材料,并对其结构进行了表征.以六方孔道结构的介孔氧化硅模板获得了直径为7 nm的金属铜纳米线阵列;以笼状体心立方孔道结构的模板获得了具有哑铃状形貌的铜单质纳米颗粒.对于氧化锌纳米结构,电化学沉积过程使得氧化锌完全填充氧化硅模板的孔道,分别得到了具有六方和体心立方介孔结构的ZnO/SiO2纳米复合物薄膜.

By using mesoporous silica thin films with different porestructure as templates, employing an electrodeposition method, Cu an ZnO nanostructures were synthesized and characterized respectively. By using hexagonal mesostructured template, metal Cu nanowires with diameter of 7 nm were derived and by using body-centered mesostructured template, Cu nanoparticles with dumbbell-like morphology were obtained. As for the ZnO nanostructures, channels of the silica templates were fully occupied with the semiconductor, and ZnO/SiO2 nanocomposites with different mesostructure were prepared. This approach can be further expended to nanostructures with alternative components, which provided a new method for synthesizing small-sized nanostructures by electrodeposition.

Key words: electrodeposition, nanostructure, mesoporous material, template, film
