Titanium dioxide is one of the most studied materials nowadays. TiO2 nanotubular membranes find their applications in solar energy conversion, hydrogen sensing, catalysis for decomposition of organic materials, in biomedical applications, etc. In this paper we propose an electrochemical cost-effective method for obtaining both-ends opened nanotubular membranes. The method implies several stages: the first anodization step for a short period of time followed by removal of the formed oxide, the second anodization for growing the membrane, and a final stage of detaching the membrane from the metal surface. By choosing the appropriate parameters for each stage we can fabricate nanotubular membrane with large specific surface and identical nanotube sizes. |
