摘要： 以胶体碳球为模板, 廉价的硝酸铝为铝源, 成功制备出了新型的大小可控的氧化铝空心球. 通过透射电子显微镜(TEM)、扫描电子显微镜(SEM)、能量扩散X射线(EDX)、X射线粉末衍射(XRD)等手段对合成产品进行了表征, 并考察了不同合成条件对空心球形貌的影响. 实验结果表明, 合成的氧化铝空心球大小均一, 粒径及壁厚均可调节. 在该实验条件下, 硝酸铝浓度及吸附时间的改变对产品结果没有明显的影响, 而吸附温度的改变引起了产品表面光滑度及壁厚的改变.

Abstract: Novel size-tunable alumina hollow spheres were successfully prepared using colloidal carbon spheres as templates and aluminum nitrate as alumina source. The samples were characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive X-ray (EDX), and X-ray diffraction (XRD). The influences of the synthesis conditions such as reaction time, reaction temperature, and the concentration of Al(NO3)3 were studied. According to the experiment, the synthesized alumina hollow spheres with a narrow size distribution showed tunable shell thickness and uniform shell. The morphology of the alumina hollow spheres was influenced mainly by the reaction temperature.
