ABSTRACT

Nano-materials is the 21st century and new materials, the concept was attention and in-depth development.in the middle of last century the scientific community to give extensive. Now, nano-materials has been in defense, electronics, metallurgy, chemistry, medicine and other fields shows a good prospect, is the new material on the most dynamic, social development has an important impact on the study.
Nano-TiO2 as a new type of inorganic semiconductor materials, because of its excellent performance, a variety of purposes, the broad application of enticing prospects of its early research in the last century to the 1970s has been carried out since the ascendant. At present, the Nano TiO2 powder and nano-thin film of the more common, and the reports of TiO2 nanotube little. TiO2 nanotube has a greater surface area and thus has a higher surface energy than the nano-powder, the film.It is expected in a wide range of practical applications with better nature. So the research to TiO2 nanotube is not only a theoretical significance and value highly the subject.
By using anodic alumina film as a template, anodic alumina template in the formation of holes used by Sol - gel REE doping prepared by the TiO2 nanotube, using transmission electron microscopy, X-ray diffraction, and other means of testing the TiO2 Nanotubes of the morphology, structure and composition were characterized, and the formation mechanism of theoretical analysis. Using transmission electron microscopy TiO2 nanotube on the length and diameter were characterized and found that under the conditions of the test system in the TiO2 nanotube uniform size, diameter of about 80 ~ 130 nm, diameter of 50 ~ 70 nm; X-ray results showed that the After a certain temperature roasting after the TiO2 nanotube crystal for anatase, the surface area for analysis shows that TiO2 nanotube surface area generally larger than TiO2 nano-powder surface area.


Keywords: rare earth, template, sol-gel, titanium dioxide, nanotube
