本文报道了在可控的气体环境和温度条件下,用环境扫描透射电子显微镜(ESTEM)在单原子水平上实时观察和分析气固催化剂动态反应的研究进展。ETEM的最新发展使其能够在催化反应的工作状态下检测基本的单原子及其相关的固体非均相催化剂的原子结构。新的数据在基本水平上提高了对动态原子过程和反应机制的理解,包括活性和失活;在化学基础上的重要技术过程。原子分辨率- e (S)TEM对科学和技术的好处包括导致改进技术过程的新知识,减少能源需求和更好地管理环境废物。本文是讨论会议“与结构和功能相关的动态显微镜”的一部分。
Progress is reported in analyticalin situenvironmental scanning transmission electron microscopy (ESTEM) for visualizing and analysing in real-time dynamic gas–solid catalyst reactions at the single-atom level under controlled reaction conditions of gas environment and temperature. The recent development of the ESTEM advances the capability of the established ETEM with the detection of fundamental single atoms, and the associated atomic structure of selected solid-state heterogeneous catalysts, in catalytic reactions in their working state. The new data provide improved understanding of dynamic atomic processes and reaction mechanisms, in activity and deactivation, at the fundamental level; and in the chemistry underpinning important technological processes. The benefits of atomic resolution-E(S)TEM to science and technology include new knowledge leading to improved technological processes, reductions in energy requirements and better management of environmental waste.This article is part of a discussion meeting issue ‘Dynamicin situmicroscopy relating structure and function’.
