TiO2 Nanowires/Nanobelts Originating from Anodically Grown Nanotube Arrays

摘要：

TiO2 nanotube arrays have aroused great interest because of their enormous application in areas such as gas sensor,catalysts,biological materials,and solar cells.In this report,TiO2 nanowires/nanobelts originating from TiO2 nanotube arrays are fabricated by simple anodization of Ti foils in ethylene glycol (EG)containing 0.25wt％ NH4F.From the field emission scanning electron microscopy(FE-SEM)it is observed that the morphology of the special structure is influenced by anodization voltage,water content and anodization time.In these factors,small amount of water plays a very important role in making the special nanostructure.Moreover,a possible mechanism that showed a relationship between the formation of the special structure and electric field directed chemical etch is proposed.
