几十年来，差动泵浦环境透射电子显微镜一直是研究气体环境下催化剂动态结构演化的有力工具。随着基于微机电系统的技术的进步，窗口气室由于其能够实现高压并且只需最少的修改即可兼容各种显微镜而变得越来越受欢迎。这使得一系列成像和分析技术成为可能，例如原子分辨率成像、光谱学和操作，揭示了前所未有的细节。通过回顾最近的一些工作，我们证明了窗口气体电池具有解决复杂催化问题的独特能力。我们还讨论了需要解决的技术难题，并对原位环境透射电子显微镜（TEM）技术及其在催化开发领域的应用的未来进行了展望。
For decades, differentially pumped environmental transmission electron microscopy has been a powerful tool to study dynamic structural evolution of catalysts under a gaseous environment. With the advancement of micro-electromechanical system-based technologies, windowed gas cell became increasingly popular due to its ability to achieve high pressure and its compatibility to a wide range of microscopes with minimal modification. This enables a series of imaging and analytical technologies such as atomic resolution imaging, spectroscopy, and operando, revealing details that were unprecedented before. By reviewing some of the recent work, we demonstrate that the windowed gas cell has the unique ability to solve complicated catalysis problems. We also discuss what technical difficulties need to be addressed and provide an outlook for the future of in situ environmental transmission electron microscopy (TEM) technologies and their application to the field of catalysis development.
