本文介绍了原子分辨环境（扫描）透射电子显微镜（E（S）TEM）在控制气体环境和温度的反应条件下，在原子水平上原位探测气固催化反应的进展。ETEM的最新发展扩展了ETEM的能力，通过提供单个原子的直接可视化和选定的固态多相催化剂在其工作状态下的原子结构的实时。原子分辨率E（S）TEM提供了对固体表面动态原子过程及其操作机制的更深入理解。原子分辨率-E（S）TEM对科学和技术的好处包括新知识，这些新知识导致改进的技术过程，具有巨大的经济效益，改善医疗保健，减少能源需求和管理环境废物的产生。(C)2014年，科学院。由Elsevier Masson SAS出版。All rights reserved.
Advances in atomic resolution Environmental (Scanning) Transmission Electron Microscopy (E(S)TEM) for probing gas solid catalyst reactions in situ at the atomic level under controlled reaction conditions of gas environment and temperature are described. The recent development of the ESTEM extends the capability of the ETEM by providing the direct visualisation of single atoms and the atomic structure of selected solid state heterogeneous catalysts in their working states in real-time. Atomic resolution E(S)TEM provides a deeper understanding of the dynamic atomic processes at the surface of solids and their mechanisms of operation. The benefits of atomic resolution-E(S)TEM to science and technology include new knowledge leading to improved technological processes with substantial economic benefits, improved healthcare, reductions in energy needs and the management of environmental waste generation.
