The advancement of clean energy and environment depends strongly on the development of efficient catalysts in a wide range of heterogeneous catalytic reactions, which has benefited from transmission electron microscopic techniques in determining the atomic-scale morphologies and structures. However, it is the morphology and structure under the catalytic reaction conditions that determine the performance of the catalyst, which has captured a surge of interest in developing and applying in situ/operando transmission electron microscopic techniques in heterogeneous catalysis. The major theme of this review is to highlight some of the most recent insights into heterogeneous catalysts under the relevant reaction conditions using in situ/operando transmission electron microscopic techniques. Rather than a comprehensive overview of the basic principles of in situ/operando techniques, this review focuses on the insights into the atomic-scale/nanoscale details of various catalysts ranging from single-component to multicomponent catalysts under heterogeneous catalytic, electrocatalytic, and photocatalytic reaction conditions involving both gas–solid and liquid–solid interfaces. This focus is coupled with discussions of the correlation of the atomic, molecular, and nanoscale morphology, composition, and structure with the catalytic properties under the reaction conditions, shining light on the challenges and opportunities in design of nanostructured catalysts for clean and sustainable energy applications.

通过原位/操作电子显微镜观察反应条件下的多相催化剂

清洁能源和环境的进步在很大程度上取决于在广泛的非均相催化反应中开发高效催化剂，这得益于透射电子显微镜技术在确定原子级形态和结构方面的作用。然而，催化反应条件下的形貌和结构决定了催化剂的性能，这引起了人们在多相催化中开发和应用原位/原位透射电子显微镜技术的兴趣。本综述的主要主题是强调使用原位/操作透射电子显微镜技术在相关反应条件下对非均相催化剂的一些最新见解。本综述不是对原位/操作技术的基本原理进行全面概述，而是侧重于对多相催化、电催化和光催化反应下从单组分到多组分催化剂的各种催化剂的原子级/纳米级细节的深入了解涉及气固界面和液固界面的条件。这一焦点与原子、分子和纳米级形态、组成和结构与反应条件下催化性能的相关性的讨论相结合，揭示了设计用于清洁和可持续能源应用的纳米结构催化剂的挑战和机遇. 本综述的重点是深入了解在涉及气固和液固界面的多相催化、电催化和光催化反应条件下，从单组分到多组分催化剂的各种催化剂的原子级/纳米级细节。这一焦点与原子、分子和纳米级形态、组成和结构与反应条件下催化性能的相关性的讨论相结合，揭示了设计用于清洁和可持续能源应用的纳米结构催化剂的挑战和机遇. 本综述的重点是深入了解在涉及气固和液固界面的多相催化、电催化和光催化反应条件下，从单组分到多组分催化剂的各种催化剂的原子级/纳米级细节。这一焦点与原子、分子和纳米级形态、组成和结构与反应条件下催化性能的相关性的讨论相结合，揭示了设计用于清洁和可持续能源应用的纳米结构催化剂的挑战和机遇.
