钒氧化物纳米带的合成及其去除水中Cu2+离子的研究

摘要

Vanadium oxide nanobelts are firstly prepared in a mixed salts electrolyte by a simple electrochemical anodization method. The constitution, structures and properties of the as-prepared samples are characterized by X-ray diffraction (XRD), thermogravimetric analysis/differential scanning calorimetry (TG/DSC) and high-resolution transmission electron microscopy (HRTEM). The nanobelts have the length of 0.5-3 μm and the width of 20-50 nm. They can absorb 99.0% Cu2+from aqueous solution.%首次通过电化学阳极氧化钒箔,在混合盐电解液中合成出了钒氧化物纳米带.采用X射线衍射(XRD)、综合热分析(TG/DSC)和高分辨透射电子显微镜(HRTEM)等对产物的组成、结构和形貌进行了表征.钒氧化物纳米带的长度在0.5-3.0 μm之间,宽度在20-50 nm之间,对水中Cu2+的吸附率可以达到99.0%.
