以V2O5和KHSO4为原料，在无表面活性剂和模板剂的条件下，在水热条件下合成了K2V8O21单晶纳米带。用X射线衍射仪、X射线光电子能谱、扫描电子显微镜和透射电子显微镜对所合成的纳米带进行了表征。纳米带本质上是单晶的，典型的宽度为100-500 nm，厚度小于100 nm，长度可达几十微米。考察了溶液浓度、反应温度和K/V摩尔比对产物形貌和物相组成的影响。并对可能的形成机理进行了探讨。(C)2010年爱思唯尔有限公司和Techna Group S.r.l.版权所有。
Single-crystal K2V8O21 nanobelts were prepared from the reaction between V2O5 and KHSO4 under hydrothermal condition using no surfactant or template. The synthesized nanobelts were characterized by X-ray diffraction, X-ray photon-electron spectrometry, scanning electron microscopy, and transmission electron microscopy. The nanobelts are single-crystalline in nature, and have typical width of 100-500 nm, thickness of less than 100 nm and length up to a few tens of microns. The effects of solution concentration, reaction temperature and molar ratio of K and Von the morphology and phase component of the obtained products have been investigated. The possible formation mechanism was also discussed. (C) 2010 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
