论文摘要
搜索具有净零碳排放的新能量范式需要新技术用于能源产生和存储，这是工程，化学，物理，物理，表面和材料科学之间的十字路口。为了继续推动设备性能和寿命的固有界限，我们需要远离厨师和外观的方法，并旨在建立科学的基础来指导新材料的设计。这需要在多个尺度上建立显微镜和光谱技术之间建立桥梁的巨大努力。在这里，我们讨论如何在表面和子表面的研究中利用基于X射线和电子的光谱和原子探针断层扫描的互补性，以了解电催化剂中的结构 - 特质关系。
The search for a new energy paradigm with net-zero carbon emissions requires new technologies for energy generation and storage that are at the crossroad between engineering, chemistry, physics, surface and materials sciences. To keep pushing the inherent boundaries of device performance and lifetime, we need to step away from a cook-and-look approach and aim to establish the scientific ground to guide the design of new materials. This requires strong efforts in establishing bridges between microscopy and spectroscopy techniques, across multiple scales. Here, we discuss how the complementarities of X-ray- and electron-based spectroscopies and atom probe tomography can be exploited in the study of surfaces and sub-surfaces to understand structure-property relationships in electrocatalysts.
