In this work, we report a simple "one pot" approach to prepare hollow anatase TiO nanospheres via Ostwald ripening under hydrothermal conditions. Inner nanospace and highly organized crystallites in the shell structure and surface regions can be created with a wide range of controlling parameters. The formation mechanism has been investigated with TEM/ED/SEM/EDX/XRD/XPS methods. The approach shows a high versatility for structural engineering of various targeted morphological products, including inner material refills.
在本工作中，我们报道了一种简单的“一锅法”，即在水热条件下通过奥斯特瓦尔德熟化制备中空锐钛矿型TiO纳米球。通过一系列可控参数，可以在壳结构和表面区域形成内部纳米空间以及高度有序的微晶。利用透射电子显微镜/电子衍射/扫描电子显微镜/能量散射X射线光谱/ X射线衍射/ X射线光电子能谱方法对形成机理进行了研究。该方法对于各种目标形态产物的结构工程，包括内部材料填充，显示出高度的通用性。
