Under control: The low temperature oxidation activity of diesel oxidation catalysts was improved by unraveling the dynamic structural behavior of Pt nanoparticles on ceria using operando X-ray absorption spectroscopy (XAS) and environmental transmission electron microscopy (ETEM). This led to a general concept to finely adjust the size and structure of noble metal particles on strongly interacting supports during real operation.

调节二氧化铈原位上的铂颗粒结构，以提高废气催化剂的催化性能

在控制下：使用操作X射线吸收光谱（XAS）和环境透射电子显微镜（ETEM）揭示了氧化铈上Pt纳米颗粒的动态结构行为，从而改善了柴油氧化催化剂的低温氧化活性。这导致了一个一般概念，即在实际操作过程中精细调整强相互作用载体上的贵金属颗粒的尺寸和结构。
