The interaction and stability of Ru 4 POM on few layer graphene via functional groups is investigated by time‐dependent imaging using aberration‐corrected transmission electron microscopy. The Ru 4 POM demonstrates dynamic motion on the graphene surface with its frequency and amplitude of rotation related to the nature of the functional group used. The stability of the Ru 4 POM–graphene hybrid corroborates its long‐term robustness when applied to multielectronic catalytic processes.
