在表面活性剂聚(N-乙烯基-2-吡咯烷酮)存在下,通过将CuSO4·5H2O和CS2溶液在140℃水热处理18h,成功制备了CuS三维纳米结构。采用X射线衍射、扫描电子显微镜、透射电子显微镜和紫外可见分光光度计对CuS进行了表征。组装而成的三维纳米结构直径约为100nm,由厚度为20nm的六方CuS纳米片组成。研究了聚(N-乙烯基-2-吡咯烷酮)、反应温度和反应时间等合成参数对产物形貌的影响。讨论了形成三维花状纳米结构的可能机制。
CuS three-dimensional nanoarchitectures have been successfully prepared in the presence of surfactant Poly(N-vinyl-2-pyrrolidone) by hydrothermally treating the solution of CuSO4·5H2O and CS2at 140°C for 18h. X-ray diffraction, scanning electron microscope, transmission electron microscope, and ultraviolet–visible spectrophotometer were used to characterize the CuS. The assembled three-dimensional nanoarchitecture, with a diameter of about 100nm, was composed of hexagonal CuS nanoplates with a thickness of 20nm. The influences of synthetic parameters, such as Poly(N-vinyl-2-pyrrolidone), reaction temperature and reaction time, on the morphologies of the products have been investigated. The possible mechanism of forming three-dimensional flower-like nanoarchitecture was discussed.
