Establishing structure–activity relationships for practical catalysts requires a multi-technique operando approach. Using advanced spectroscopic tools and kinetic methods the catalytic role of different Pd oxidation states in CO oxidation was unveiled for Pd/CeO₂ catalysts. Single-atom Pd–oxo species and Pd−O−Ce interface are responsible for low-temperature activity, whereas metallic Pd sites significantly contribute only at elevated temperature.

操作光谱揭示了不同钯氧化态在 Pd/CeO2 催化剂上 CO 氧化中的催化作用

建立实用催化剂的构效关系需要多种技术操作方法。_{使用先进的光谱工具和动力学方法，揭示了 Pd/CeO 2}催化剂在 CO 氧化中不同 Pd 氧化态的催化作用。单原子 Pd-oxo 物种和 Pd-O-Ce 界面负责低温活性，而金属 Pd 位点仅在高温下显着贡献。
