Cerium oxide is a very interesting material that finds applications in many different fields, such as catalysis, energy conversion, and biomedicine. An interesting approach to unravel the complexity of real systems and obtain an improved understanding of cerium oxide-based materials is represented by the study of model systems in the form of epitaxial ultrathin films or nanostructures supported on single crystalline substrates. These materials often show interesting novel properties, induced by spatial confinement and by the interaction with the supporting substrate, and their understanding requires the use of advanced experimental techniques combined with computational modeling. Recent experimental and theoretical studies performed within this field are examined and discussed here, with emphasis on the new perspectives introduced in view of the optimization of cerium oxide-based materials for application in different fields.
氧化铈是一种非常有趣的材料，在许多不同领域都有应用，如催化、能量转换和生物医学。一种揭示实际系统复杂性并增进对氧化铈基材料理解的有趣方法是研究以单晶衬底上的外延超薄膜或纳米结构形式存在的模型系统。这些材料常常展现出由空间限制以及与支撑衬底的相互作用所诱导的有趣新特性，而对它们的理解需要结合先进的实验技术和计算建模。本文将审视和讨论该领域内近期进行的实验和理论研究，重点关注鉴于优化氧化铈基材料以应用于不同领域而引入的新视角。
