在中温密闭反应器中，采用一种简单、环境友好的方法成功制备了六方结构的NbSe 2纳米片。微米尺寸的Nb和Se的球磨混合物之间的热（750 ℃）固态反应产生高产率的NbSe 2纳米片。采用XRD、EDS和SEM对产物进行了表征。结果表明，所制备的NbSe2纳米片为六方相，尺寸均匀，NbSe2纳米片的形成经历了一系列的相变过程。根据不同温度下的实验结果，提出了合理的反应过程和形成机理。此外，球磨时间对获得均匀分布的纳米片起着至关重要的作用。(C)2014爱思唯尔有限公司版权所有。
The NbSe2 nanoplates with hexagonal morphology have been successfully prepared by a facile, environmentally friendly reaction in closed reactor at moderate temperature. The thermal (750 degrees C) solid-state reaction between the ball-milled mixture of micro-sized Nb and Se yielded a high yield of NbSe2 nanoplates. The as-prepared products were characterized by XRD, EDS, and SEM. The results showed that the as-prepared products were hexagonal phase NbSe2 nanoplates with uniform sizes and the formation of NbSe2 nanoplates underwent a series of phase transition. On the basis of experimental results obtained at different temperatures, a reasonable reaction process and a formation mechanism were proposed. Moreover, the ball milling time played a crucial role in acquiring the homogeneous distribution nanoplates. (C) 2014 Elsevier Ltd. All rights reserved.
