以聚乙烯吡咯烷酮为封端剂，通过溶剂热反应合成了高结晶度的二硒化锰（MnSe 2）纳米棒。采用扫描电子显微镜、透射电子显微镜、电子能量损失谱、粉末X射线衍射和能量色散X射线能谱等手段对样品的尺寸、形貌、结构和相纯度进行了表征。结果表明，所合成的MnSe 2纳米棒沿[200]轴沿着生长，具有较高的结晶度。此外，MnSe 2纳米棒的纵横比范围从10.15到10.70可以通过简单地改变聚乙烯吡咯烷酮的量来调节。此外，N，N-二甲基甲酰胺与去离子水的体积比对产物的形貌和组成有重要影响。此外，研究了MnSe 2纳米棒的微波吸收性能。研究表明，MnSe 2纳米棒作为微波吸收材料具有潜在的应用前景。
Highly crystalline manganese diselenide (MnSe2) nanorods were synthesized via a facile solvothermal reaction with polyvinylpyrrolidone as a capping agent. The size, morphology, structure as well as phase purity were characterized by scanning electron microscopy, transmission electron microscopy, electron energy loss spectroscopy, powder X-ray diffraction, and energy-dispersive X-ray spectroscopy. All the results demonstrated that the as-synthesized MnSe2nanorods grow along [200] axis and have high crystallization degree. Moreover, the aspect ratio of the MnSe2nanorods ranging from ∼15 to ∼70 can be tuned by simply changing the amount of polyvinylpyrrolidone. Besides, the volume ratio of N,N-dimethylformamide to deionized water has critical influence on the morphology and composition of the products. Moreover, the microwave absorption properties of the MnSe2nanorods were investigated. All the studies indicate that the MnSe2nanorods might have potential applications as promising microwave absorbing materials.
