摘　　要：分别以五氧化二钒为钒源、双氧水为溶剂和以偏钒酸铵为钒源、稀硫酸为溶剂,通过低温水热法合成了五氧化二钒纳米带和纳米板。并利用X射线衍射(XRD)、傅里叶红外光谱(FT-IR)和场发射扫描电镜(SEM)对产物进行表征。结果表明,反应产物均为正交的五氧化二钒晶型,纳米带宽度100～300 nm,厚度约100 nm左右,纳米板形状规则,分布较为均匀,厚度在纳米级别。Vanadium pentoxide nano-belts and nano-plate are synthesized by a low temperature hydrothermal method using vanadium pentoxide as vanadium source,hydrogen peroxide as the solvent and ammonium metavanadate as vanadium source,dilute sulfuric acid as the solvent respectively.The products are characterized by X-Ray Diffraction(XRD),Fourier Infrared Spectrum(FT-IR)and Field Emission Scanning Electron Microscopy(SEM).The results show that the reaction products are all composed of orthogonal vanadium pentoxide.The nano-belts are 100-300 nm in width and 100 nm around in thickness.And the nano-plates are nanometer level in thickness with regular shape and uniform distribution.
