利用相应的金属单质纳米线作为自牺牲模板，通过气固硫化反应成功制备了由弯曲CdS纳米管组成的大尺寸纳米海绵。通过X射线粉末衍射、透射电子显微镜、场发射扫描电子显微镜和光致发光光谱对产物进行了表征。根据实验结果，可以用柯肯德尔效应来描述生长途径。此外，CdS 纳米管在可见光照射下对不可生物降解的罗丹明 B 的降解表现出很高的光催化活性，这可能是由于内表面和外表面均可通过壁上的孔进入。 (C) 2010 Elsevier B.V. 保留所有权利。
Using corresponding metal elemental nanowires as a self-sacrificed template, large-scale nanosponges consisted of curving CdS nanotubes have been successfully fabricated through a gas-solid sulfurization reaction. The products were characterized by X-ray powder diffraction, transmission electron microscopy, field-emission scanning electron microscopy and photoluminescence spectrum. The growth pathway can be described in terms of Kirkendall effect based on the experimental results. Furthermore, the CdS nanotubes exhibit high photocatalytic activity for degradation of the nonbiodegradable rhodamine B under visible irradiations probably due to the accessibility of both inner and outer surfaces through the pores in the walls.
