Popis:	Two-dimensional (2D) layered antimony (Sb) and antimony telluride (Sb2 Te3 ) 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 Sb2 Te3 have been obtained by electrochemical exfoliation. The layered rhombohedral Sb was exfoliated in Na2 SO4 and Li2 SO4 electrolytes by anodic-cationic intercalation, and Sb2 Te3 was exfoliated in Na2 SO4 . 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.
