Abstract Room‐temperature synthesis of 2D graphitic materials (2D‐GMs) remains an elusive aim, especially with electrochemical means. Here, it is shown that liquid metals render this possible as they offer catalytic activity and ultrasmooth templating interface promotes Frank–van der Merwe regime growth, while allowing facile exfoliation due to the absence interfacial forces a nonpolar liquid. The 2D‐GMs are formed at low onset potential can be in situ doped depending on choice organic precursors set‐up. tuned exhibit porous or pinhole‐free morphologies engineered for their degree oxidation number layers. proposed liquid‐metal‐based room‐temperature route expanded many other materials.
