采用高通量连续水热流合成技术制备了Ce-Zr-Y-O体系中66种独特的纳米结构氧化物样品。这种合成方法与传统的分批或连续水热合成方法相比，产量显著增加。将所制备的库样品置于孔板中用于自动化高通量粉末X射线衍射和拉曼光谱数据收集，这允许全面的结构表征和相位映射。结果表明，Ce-Zr-O、Ce-Y-O和Y-Zr-O三个二元系之间存在一个连续的类γ相场，其相邻组分之间的结构发生了平稳的转变。连续的水热过程导致所制备的微晶尺寸在2-7 nm的范围内（如通过使用Scherrer方程所确定的）。
High-throughput continuous hydrothermal flow synthesis was used to manufacture 66 unique nanostructured oxide samples in the Ce–Zr–Y–O system. This synthesis approach resulted in a significant increase in throughput compared to that of conventional batch or continuous hydrothermal synthesis methods. The as-prepared library samples were placed into a wellplate for both automated high-throughput powder X-ray diffraction and Raman spectroscopy data collection, which allowed comprehensive structural characterization and phase mapping. The data suggested that a continuous cubic-like phase field connects all three Ce–Zr–O, Ce–Y–O, and Y–Zr–O binary systems together with a smooth and steady transition between the structures of neighboring compositions. The continuous hydrothermal process led to as-prepared crystallite sizes in the range of 2–7 nm (as determined by using the Scherrer equation).
