Abstract:
Although many two‐dimensional (2D) hybrid nanostructures are being prepared, the engineering of epitaxial 2D semiconductor hetero‐nanostructures in the liquid phase still remains a challenge. The preparation of 2D semiconductor hetero‐nanostructures by epitaxial growth of metal sulfide nanocrystals, including CuS, ZnS and Ni 3 S 2 , is achieved on ultrathin TiS 2 nanosheets by a simple electrochemical approach by using the TiS 2 crystal and metal foils. Ultrathin CuS nanoplates that are 50–120 nm in size and have a triangular/hexagonal shape are epitaxially grown on TiS 2 nanosheets with perfect epitaxial alignment. ZnS and Ni 3 S 2 nanoplates can be also epitaxially grown on TiS 2 nanosheets. As a proof‐of‐concept application, the obtained 2D CuS–TiS 2 composite is used as the anode in a lithium ion battery, which exhibits a high capacity and excellent cycling stability.
