Two-dimensional (2D) layered antimony (Sb) and antimony telluride (Sb Te ) 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 Te have been obtained by electrochemical exfoliation. The layered rhombohedral Sb was exfoliated in Na SO and Li SO electrolytes by anodic-cationic intercalation, and Sb Te was exfoliated in Na SO . 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.
二维（2D）层状锑（Sb）和碲化锑（Sb₂Te₃）是用于光电器件和热电应用的两种有价值的材料。制备这些材料的高质量薄片是推动其预期应用的初始阶段。在此，通过电化学剥离获得了微米级的少层至多层Sb和Sb₂Te₃薄片。层状菱面体Sb通过阳极阳离子插层在Na₂SO₄和Li₂SO₄电解质中被剥离，而Sb₂Te₃在Na₂SO₄中被剥离。这些发现对于基于溶液的室温电化学剥离是重要贡献，该方法在无手套箱条件下稳定，有助于进一步提高高质量剥离薄片的产量。
