报道了定制纳米结构氧化钒钼（VxMo1-xOy）体系的合成和表征。透射电镜研究清楚地表明，在富钒和富钼端形成了不同的形态。提出了这些不同的形貌对表面面积的影响。结果表明，x < 0.40的组合物具有电子导电性，离子导电性的贡献减小。对这一现象的可能解释进行了讨论。VMO体系在超级电容器等领域作为电极材料具有广阔的应用前景。(C) 2008 Elsevier Ltd版权所有。
Synthesis and characterization of the tailored nanostructured vanadium molybdenum oxide (VxMo1-xOy) system is reported. TEM studies clearly show the formation of varying morphologies at vanadium and molybdenum rich ends. The effect of these differing morphologies on the surface area is presented. It is shown that compositions with x < 0.40 have electronic conductivity and a reduced contribution of ionic conductivity. Possible explanations for this observation are discussed. The VMO system shows promise for application as electrode materials in fields such as supercapacitors. (C) 2008 Elsevier Ltd. All rights reserved.
