摘要

研究了一种在常压下产生的O2/Ar/H2微波等离子体中分解气相VOCl3制备V2O5粉末的新方法。从等离子体反应器不同位置采集的样品为纳米结构粉末，呈黄色，是典型的纳米尺寸颗粒;微观结构粉末呈黄橙色，有大片的地毯或海绵状区域，由一束V2O5针状组成。采用EDX、SEM、XRD、Raman和TEM对样品进行了分析。

Preparation of vanadium pentoxide powders by microwave plasma-torch at atmospheric pressure

A new method for preparing V₂O₅ powders has been developed, which is based on decomposition of gas-phase VOCl₃ in O₂/Ar/H₂ microwave plasma generated at the atmospheric pressure. The samples taken from different positions of the plasma reactor were the nano-structured powder, which was yellow and typical nano-sized particles, and the micro-structured powder, which was yellowish orange, had large carpet- or sponge-like areas, and was composed of a bundle of V₂O₅ needles. These two samples have been analyzed by EDX, SEM, XRD, Raman and TEM.
