Two‐dimensional (2D) layered antimony (Sb) and antimony telluride (Sb 2 Te 3 ) are two valuable materials for optoelectronic devices and thermoelectric applications. Preparing high‐quality sheets of these materials is the initial phase to promote their expected issues. Herein, micrometer‐sized few‐to‐multilayered sheets of Sb and Sb 2 Te 3 have been obtained by electrochemical exfoliation. The layered rhombohedral Sb was exfoliated in Na 2 SO 4 and Li 2 SO 4 electrolytes by anodic–cationic intercalation, and Sb 2 Te 3 was exfoliated in Na 2 SO 4 . These findings are important contributions for the solution‐based room‐temperature electrochemical exfoliation, which is stable under glove‐box‐free conditions, to further improve the production of high‐quality exfoliated sheets.
