Here, we develop an <em>in situ</em> environmentaltransmission electron microscopy (ETEM) platform that integrates simultaneouslight illumination, electrical biasing, and controlled water vaporexposure within a commercially available chip, supplemented with acustomized optical add-on. This multistimulus configuration enablesreal-time atomic-scale imaging of PEC materials under conditions closelyresembling operation. Applying this platform to Ta₃N₅, we directly capture its structural evolution under combinedstimuli and reveal a previously unresolved degradation pathway involvingnanocrystal detachment, migration, and inward-propagating amorphization.These processes lead to the growth of amorphous surface layers thatare directly associated with performance loss in operating photoanodes.More broadly, this work establishes a mechanistic framework linkingnanoscale structural transformations to macroscopic device degradation,providing concrete targets for stabilization strategies in Ta₃N₅ and related metastable PEC materials.
