采用水热法合成了由纳米带构成的新型巢状（NH4）（2）V6O16中心点1.5H（2）O结构。粉末X射线衍射分析表明，样品为单斜晶相（NH_4）（2）V_6O_（16）中心点1.5H（2）O。在130 ° C下持续3天获得的样品的扫描电子显微镜图像表现出巢状形态。透射电子显微镜的结果表明，纳米带具有光滑的表面。纳米带的选定区域电子衍射图案表明单晶性质。在热重分析中发生两种主要的重量损失，其对应于水和氨分子的去除。（NH_4）（2）V_6O_（16）中心点1.5H（2）O产物经煅烧后形成斜方晶系的斜方钒矿相V_2O_5。(C)© 2014 Elsevier B.V.保留所有权利。
Novel nest-like (NH4)(2)V6O16 center dot 1.5H(2)O structures made of nanobelts have been synthesized by a facile hydrothermal approach. The powder X-ray diffraction pattern of the sample reveals the monoclinic crystalline phase of (NH4)(2)V6O16 center dot 1.5H(2)O. The scanning electron microscopy images of the sample obtained at 130 degrees C for 3 days exhibit nest-like morphology. The transmission electron microscopy result reveals that the nanobelts have a smooth surface. The selected area electron diffraction pattern of the nanobelts indicates single crystalline nature. The two major weight losses occur in thermogravimetric analysis which correspond to the removal of water and ammonia molecules. Further, calcination of the (NH4)(2)V6O16 center dot 1.5H(2)O product results in the formation of orthorhombic phase of shcherbianite V2O5. (C) 2014 Elsevier B.V. All rights reserved.
