通过VO2(B)纳米带在高温下的不可逆相变制备了VO2(R)纳米带。VO2(R)纳米带的形状和尺寸取决于前驱体的形状和尺寸。采用水热法合成了VO2(B)纳米带，并讨论了VO2(B)纳米带的形成过程。采用X射线衍射仪、透射电子显微镜、FE-SEM、HRTEM、DTA、FT-IR等技术对产物进行了表征。所得VO2(R)纳米带为单斜晶系，长350-600 nm，宽100-150 nm，厚度20-30 nm。
VO2(R) nanobelts were prepared by the irreversible transformation of VO2(B) nanobelts at the elevated temperature. The morphology and size of the VO2(R) nanobelts were dependent on that of the precursor. VO2(B) nanobelts were synthesized by a hydrothermal route, and the process of the VO2(B) nanobelts' formation was also discussed. The product was characterized by a combination of techniques including XRD, TEM, FE-SEM, HRTEM, DTA and FT-IR. The as-obtained VO2(R) nanobelts have a monoclinic structure with a length of 350–600 nm, a wideness of 100–150 nm and a thickness of 20–30 nm.
