| Abstract: | Electrochemical Atomic Force Microscopy (EC‐AFM) has become a powerful tool for visualising dynamic processes at electrode/electrolyte interfaces with a nanoscale resolution. This technique enables real‐time monitoring of morphological, chemical, and structural changes in electrocatalysts under operating conditions, providing critical insights into the mechanisms of electrocatalytic reactions. In this review, I introduce some applications of EC‐AFM in electrocatalysis research and experimental considerations. The applications include tracking catalyst surface reconstruction, adsorption/desorption dynamics of intermediate species, long‐range probing of the electrochemical interface, and catalyst degradation analysis. Moreover, experimental challenges, including cantilever selection, liquid‐phase imaging stability, and artefacts, are discussed. Bridging the gap between nanoscale imaging and electrochemical analysis, EC‐AFM offers a unique pathway to unravel complex interfacial phenomena critical for the design of next‐generation electrocatalysts.
