Positively Charged

The adsorption of dye molecules from aqueous solution onto the surface of titanate nanotubes (which have been synthesized via an alkaline hydrothermal treatment) has been studied. The ionic charge on the dye molecules was found to affect their ability to adsorb onto the titanate nanotube surface. In the case of (cationic) methylene blue, the adsorption was preferable on the negatively charged surface of titanate nanotubes rather than on positively charged P25 TiO2 nanoparticles. In the case of (anionic) Eriochrome Black T dye, the opposite trend was found. Herein, the dynamics of dye adsorption and the effect of pH on the adsorption capacity are considered.

Titanate Nanosheets

Titanate nanotubes were successfully synthesized by means of an alkaline hydrothermal method and further appropriate post-treatments. The effect of different washing treatments on the formation of titanate nanotubes were systematically studied in this paper. It was found that the washing treatments play an important role in the formation of nanotubes. Treating with 0.1M NaCl aqueous solution mainly resulted in titanate nanosheets while treating with deionized water or 0.1M HCl aqueous solution (1 time, PH>7) can obtain highly crystallized titanate nanotubes. Furthermore, if the PH values of solutions after acid washing processes were below 7, trace of nanotubes can be found but almost all of them were damaged. On the basis of all the present experimental results, we can conclude that titanate nanotubes can be prepared as long as the driving force induced by the imbalance of sodium ion (Na+) concentration on two different sides of nanosheets was appropriate, and meanwhile they were instable in acidic solutions.
