摘要: 本文以乙二胺(En)为模板，采用溶剂热法一步合成了结晶度较好的六方相ZnSb纳米材料。通过改变En与水的浓度比，成功合成球状、棒状，以及花状的ZnSb纳米材料。实验结果表明，En浓度对ZnSb纳米结构和结晶性具有一定影响，过量的En浓度会抑制晶体生长以及破坏产物结构。基于ZnSb纳米形貌和结晶性的变化，解释了不同En与水的浓度比条件下，ZnSb纳米形貌结构形成的机理。这将为制备特殊纳米形貌结构材料，以及在电化学、热电等领域中得广泛应用提供了研究基础。
Abstract: In this paper, ZnSb nanomaterial was successfully synthesized via a facile solvothermal method with ethylenediamine (En) solvent as a template. The ZnSb nanomaterial is confirmed to be a pure hexagonal phase and has an excellent crystallinity. By regulating the En concentration ratio with H2O, ZnSb grows from nano-particles into nanorods and further nanoflower-like structure. We found that structure and crystallinity of ZnSb can be affected by the En concentration. Higher En concentration can prohibit the growth of ZnSb nanostructure. Synthesis mechanism of ZnSb under different concentration ratio between En and H2O is unveiled by the analysis of variation of mor-phology and crystallinity, which contributes to the preparation of other nanomaterials and abun-dant application of ZnSb nanomaterial in electrochemical, thermoelectrical and other fields.
