Tungsten Oxide Nanotube
When particle size of some material reaches to nano grade (1~100nm), it can show many special reactions. It can be widely applied in functional information display, catalyst, magnetic material. Among which, tungsten oxide has various crystalline structure, it has a large amount of non-stoichiometry oxide form and has multi-functional broad-band gap semiconductor material. WO 3 is widely applied in gas sensor, photocatalyst, gasochromism, electrochromism, photochromism and solar cell due to its unique electricity, optical configuation, and magnetic property. Apart from that, temperature induces structure phase transition which results in the changes of volume, resistance and color greatly draw people’s attention. The research on its special structure has become the focus of recent study. The traditional preparing method of tungsten oxide nanotube need extra coating and sculpture process, the quality of nanotube greatly depends on the control of processing steps. By coaxia...
