Energy-related catalytic reactions have been extensively investigated in past years in order to efficiently utilize clean and environmentally benign energy sources. In these systems, the catalysts and the catalyst/active medium interfaces play a crucial role in determining their performance. Thus, understanding the physical and chemical properties of catalysts during reactions is of importance to provide fundamental insights for designing the devices. Transmission electron microscopy can provide tremendous information regarding materials' morphology, microstructure, and chemical properties at nanoscales. With in situ electron microscopy, dynamic processes of catalytic reactions in both gas and liquid environments have been investigated in real time. In this paper, the recent research progress of in situ and operando electron microscopy techniques are introduced with the representative works in energy-related reactions, including electrochemical catalysis in liquid media and heterogeneous catalysis in gas media. The uniqueness of the specific electron microscopy methods and scientific merits of each work are highlighted. Finally, outlooks on emerging research opportunities are discussed.
