Tungsten Oxide Nanowire
In recent years, one-dimensional nano material such as nanowire, nanorod, nanotube are becoming popular due to its special properties. Tungsten oxide is a special N type semiconductor material, and also one of the oxide semiconductors which can realize quantum size effect. It shows great property in electrochromism, photochromism, gasochromism and is applied in various fields like chemical sensor, fuel cell and electronic device. Tungsten oxide has crystalline form of orthogonality, monoclinic, cube and hexagonal. Among which hexagonal tungsten oxide is paid much attention due to its special hexagonal panel, many metal ion can inlaying in it. So as to form hexagonal tungsten bronze MxWO 3 ( M = Li + 、Na + 、K + ). It shows great application prospect in negative electrode materials and Iithium ion rechargeable battery. Use sodium tungstate and hydrochloric acid as raw material, potassium oxalate and potassium sulphate as additive, hexagonal tungsten oxide nan...
