Facile Fabrication of Open-Ended High Aspect-Ratio Anodic TiO2 Nanotube Films and Their Applications

摘要：

　　In the present work,we demonstrated a facile process to prepare an open-ended high aspect-ratio TiO2 nanotube films through separating the anodic TNT array from the Ti substrate by a small reverse bias and opening the tube bottom by a chemical etching.The possible mechanisms of film detachment and pore opening processes have been briefly discussed.Such a process allows controlling the open-ended morphology by the straightforward chemical etching,which shows great potential in many applications,such as flow-through photocatalytic reactions,biofiltration,and diffusion controlling,and so on.An example using the open-ended TNT films is finally given as a flow-through photocatalytic reactor.The photocatalytic film has been shown to have multiple functions such as physical separation of contaminants,filtration,and decomposition of organic pollutants during diffusion.
