“…Control experiments should be performed to establish that the observed behavior is not an artifact of such contamination or cross-contamination from different electrolytes between the experiments. To avoid damaging the holders, tests involving the holder materials should also be carried out whenever corrosive electrolytes are used (see [188] for a description of such tests).…”

This review features state-of-the-art in situ and operando electron microscopy (EM) studies of heterogeneous catalysts in gas and liquid environments during reaction. Heterogeneous catalysts are important materials for the efficient production of chemicals/fuels on an industrial scale and for energy conversion applications. They also play a central role in various emerging technologies that are needed to ensure a sustainable future for our society. Currently, the rational design of catalysts has largely been hampered by our lack of insight into the working structures that exist during reaction and their associated properties. However, elucidating the working state of catalysts is not trivial, because catalysts are metastable functional materials that adapt dynamically to a specific reaction condition. The structural or morphological alterations induced by chemical reactions can also vary locally. A complete description of their morphologies requires that the microscopic studies undertaken span several length scales. EMs, especially transmission electron microscopes, are powerful tools for studying the structure of catalysts at the nanoscale because of their high spatial resolution, relatively high temporal resolution, and complementary capabilities for chemical analysis. Furthermore, recent advances have enabled the direct observation of catalysts under realistic environmental conditions using specialized reaction cells. Here, we will critically discuss the importance of spatially-resolved operando measurements and the available experimental setups that enable (1) correlated studies where EM observations are complemented by separate measurements of reaction kinetics or spectroscopic analysis of chemical species during reaction or (2) real-time studies where the dynamics of catalysts are followed with EM and the catalytic performance is extracted directly from the reaction cell that is within the EM column or chamber. Examples of current research in this field will be presented. Challenges in the experimental application of these techniques and our perspectives on the field’s future directions will also be discussed.

“…Taking advantage of its ability to achieve remarkable temporal and spatial precision while immersed in a liquid medium, liquid cell TEM technology offers a valuable means to explore diverse phenomena. These include the nucleation, growth, [7][8][9] and etching mechanisms of individual nanoparticles, 6,[10][11][12][13][14] dynamic motion of nanoparticles in liquids, [15][16][17][18] electrochemical deposition and lithiation of electrode materials, [19][20][21][22][23] as well as imaging of biomaterials in liquid environments. [24][25][26] As in situ liquid-cell TEM techniques continue to mature and their application scope expands, there has also been a gradual emergence of studies focusing on soft matter.…”

“…For example, the nucleation and growth of nanocrystals, solid electrolyte interphases during the electrodeposition of alkali metal, , structure and bonding of liquids, short-range ordering in liquid electrolyte, and many other topics have been studied. Liquid cell TEM has also been used to study nanocrystal degradation, etching, and galvanic reactions of metal. ,,− Thus, with an innovative design of experiments, it is possible to reveal corrosion pathways of materials at the nanoscale or at the atomic level using the powerful liquid cell TEM platform.…”

Unveiling materials' corrosion pathways is significant for understanding the corrosion mechanisms and designing corrosionresistant materials. Here, we investigate the corrosion behavior of Sn@Ni 3 Sn 4 and Sn nanocrystals in an aqueous solution in real time by using high-resolution liquid cell transmission electron microscopy. Our direct observation reveals an unprecedented level of detail on the corrosion of Sn metal with/without a coating of Ni 3 Sn 4 at the nanometric and atomic levels. The Sn@Ni 3 Sn 4 nanocrystals exhibit "pitting corrosion", which is initiated at the defect sites in the Ni 3 Sn 4 protective layer. The early stage isotropic etching transforms into facet-dependent etching, resulting in a cavity terminated with lowindex facets. The Sn nanocrystals under fast etching kinetics show uniform corrosion, and smooth surfaces are obtained. Sn nanocrystals show "creeping-like" etching behavior and rough surfaces. This study provides critical insights into the impacts of coating, defects, and ion diffusion on corrosion kinetics and the resulting morphologies.
