在这项工作中，我们报道了一种简单的“一锅法”，在水热条件下通过Ostwald熟化法制备锐钛矿型空心二氧化钛纳米球。利用各种控制参数，可以在壳层结构和表面区内形成高度有序的内纳米空间微晶。并用TEM/ED/SEM/EDX/XRD/XPS等方法对其形成机理进行了研究。该方法对包括内部材料填充在内的各种目标形态产品的结构工程显示出高度的通用性。
In this work, we report a simple "one pot" approach to prepare hollow anatase TiO2 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.
