Abstract

In the present study, tungsten oxide nanopowders and nanorods were synthesized by a modified plasma arc gas condensation technique. A blowing mixed gas with controllable partial oxygen pressure was introduced into the gas condensation system and tungsten oxide powders in nanoscale can be prepared. The experimental results show that yellow and blue tungsten oxide nanopowders, prepared under an Ar to O₂ ratio of 1:1 and 100:1, exhibited a major WO₃ and W₁₉O₅₅ phase, respectively. The nanoparticles grow into W₅O₁₄-phase nanorods along [001] direction when hydrogen served as the reduction gas.
