摘　　要：构建催化剂表面原子结构与催化性能之间的构效关系是目前电催化剂研究的挑战性难题,而原位透射电镜是研究材料性质-结构关系及其变化过程的有力手段,为高性能催化剂的设计及纳米科技的发展创造了新的契机。本文结合原位透射电镜技术的发展,对目前利用透射电镜原位观察电催化剂的工作进行了归纳总结,以此对具有高催化活性纳米材料的设计与构筑提供参考。It is a challenging project to identify the detailed structure-activity relationship between atomic structure and catalytic performance of electrocatalysts. In-situ transmission electron microscopy（IS-TEM）can not only provide invaluable insight into the evolution rule of material surface structure under chemical reaction environments, offer direct evidence to construct the property-structure relationship of catalyst, but also provide new opportunities for the development of nanoscience and nanotechnology. In view of ＂setting up a nanolab inside a TEM＂, we review the recent progress in the application of in-situ TEM for electrocatalyst, which will help to design and construct nanomaterials with high catalytic activity.
