纳米孔材料的性能根源是其独特的三维纳米结构。本方向将球差校正电子显微技术、原子分辨谱学技术、原子间电场表征技术、结构信息三维重构技术、原位电子显微技术等手段综合使用，在原子分辨的水平上表征纳米孔材料的表面与内部的原子结构和化学信息及其在服役期间的变化，从而揭示纳米孔材料性能的根源、为设计新型高性能的纳米孔材料提供科学指导。
The properties of nanoporous materials (NPMs) stem from their three-dimensional (3D) unique structures. This research group focuses on characterizing atomic structures and chemical information of surfaces and interiors of NPMs and their evolutions during active services at atomic resolution (AR) by combining aberration-corrected (AC) electron microscopy, AR spectroscopies, characterization of interatomic electric fields, tomography of structural information, in-situ electron microscopy and so on. These works can reveal the origins of the properties of NPMs and give scientific guides for designing new high-performance NPMs.
