A review. CeO₂ is widely used and investigated as an oxide catalyst or support due to its unique redox property of oxygen storage and release. In this paper, the different opportunities offered by Raman spectroscopy for advanced characterization of ceria-based catalysts are reviewed: spectral modifications induced by nanocrystallinity, defects, doping and reduction, identification of supported molecular species, isolated atoms and nanoclusters, characterization of surface modes, hydroxyl groups, reaction intermediates such as peroxo and superoxo species. Finally, in situ/operando studies for environmental catalysis are summarized illustrating Raman spectroscopy as a powerful tool to characterize ceria-based catalysts.

回顾。CeO ₂由于其独特的氧储存和释放的氧化还原特性而被广泛用作和研究作为氧化物催化剂或载体。在本文中，拉曼光谱为二氧化铈基催化剂的高级表征提供了不同的机会：纳米结晶引起的光谱修饰、缺陷、掺杂和还原、支持的分子种类的鉴定、孤立的原子和纳米团簇、表面模式的表征、羟基，反应中间体，如过氧和超氧物种。最后，总结了环境催化的原位/操作研究，说明拉曼光谱是表征氧化铈基催化剂的有力工具。
