| Abstract |
In this paper, urchin-like hollow sphere shaped ZnSn(OH)6 were synthesized by the 2-step hydrothermal method. During the synthesis process, the sphere shaped ZnSn(OH)6 was used as a template and formed by Pearson's hard and soft acid and base (HSABs) theory. A peculiar point is that unlike the sphere shape, the urchin-like hollow sphere shape has two phases of ZnSn(OH)6 and SnO2. Also, SnO2 rods were located at outside of urchin-like hollow sphere structure and confirmed by EDS mapping. In addition, it was characterized by Scanning electron microscopy (SEM), X-ray diffraction (XRD), and Raman spectrum. Finally, we measured quartz crystal microbalance (QCM) based on the advantage of unique shape. As a result, urchin-like hollow sphere shape has a much better sensing properties than the sphere shape. |
