采用Na₃PO₄辅助水热法合成了单晶WO₃纳米棒, 通过SEM、TEM、EDX和XRD等手段对产物进行了表征. 研究了其他无机盐(Na₂SO₄、NaNO₃和NaCl)对WO₃纳米晶形貌的影响. 实验发现 WO₃纳米棒的形成与添加Na₃PO₄密切相关, 当Na₃PO4的添加量达到50g时, 在这个反应体系中可以制得质量较好的WO₃纳米棒.

Single-crystalline WO₃ nanorods were fabricated by a hydrothermal method in the presence of Na₃PO₄. The properties of products were characterized by SEM, TEM, XRD and EDX. The effects of other alkali salts (NaCl, NaNO₃ and Na₂SO₄) on the morphologies of WO₃ nanocrystals were also investigated. The resuts show that Na₃PO₄ plays an important role in synthesizing the WO₃ nanorods. As the content of the assisted Na₃PO₄ reaches 50g, the WO₃ nanorods synthesized in this reaction system have better quality.
